How ridiculous is Liriano's slider?

Last night, Fransico Liriano worked through the Tigers lineup like a buzzsaw, using his slider to retire 10 of the 28 opponents he faced - six of which were on strikeouts. There were buckling knees and stupidly silly swings as the slider appeared to race up to the edge of the plate and diving off the table. The only mistake was a slider left up that Johnny Damon laced for a double but aside from that one transgression, Liriano was nearly flawless in Motown - as he has been for the past 23 innings. 

 

Through four starts, Liriano possesses perhaps the game's best slider. Judging from the weighted run value at Fangraphs.com, his 6.55 wSL/C is the tops among starters. Likewise for his Opponent OPS on the pitch found at MyInsideEdge.com:

 

	Pitch Value (wSL/C)	OPS against SL
2009	1.38	.586
2010	6.55	.174

*Data from Fangraphs.com and Inside-Edge.com

 

In general, his results on the slider have been much better than that of the previous season:

 

Liriano’s Slider	Chase%	Miss%	K%
2009	37	42	38
2010	54	46	54

 *Data from Inside-Edge.com

 

While there are several reasons for his overall turnabout, including an improved command of his fastball and working ahead of hitters, his rekindled slider has been his strongest offering thus far. Opponents are offering at more pitches out-of-zone and missing at a higher rate which has led to more strikeouts. His chase rate on the pitch is the highest in baseball (minimum of 100 pitches thrown) as is his miss percentage. To summarize, this is a bar whore of a slider: just all kinds of dirty.

 

Liriano’s Slider	Total Thrown	Vel (MPH) Diff.	Vert. (Inches)
2009	604	5.5	3.97
2010	124	9.1	-1.33

*Data from Fangraphs.com, TexasLeaguers.com and Inside-Edge.com

  

What makes this version so much different than a year ago? In 2009 Liriano was throwing his slider at a higher velocity. This translated to just a 5.5-mph difference with his fastball. With his increased fastball velocity in 2010, he's also toned down the MPH on his slider, decreasing the velocity on that pitch by 2-mph. This has led to a near 10-mph (9.1) separation in his fastball and slider.

 

What's more, Liriano has added more drop to his slider. As you can see in the column above (Vert.) and visually in the graphs below, the Twins lefty is getting more decline out of his breaking pitch:

*Data from TexasLeaguers.com - 2010

With everything clicking on all cylinders, it is likely that Liriano and his dirty slider will increase his scoreless inning streak in Cleveland against one of the most offensively-challenged lineups in baseball (scoring just 3.55 runs per game). 

OtB's Around the Central (04.27.10)

Chicago White Sox | 8-11 T-3rd | 5 games back

• First baseman Paul Konerko hit his league-leading 8th home run of the season on Monday and his third in as many games as the Sox won their third straight against Seattle. 
• ANALYSIS: No matter how hard they try to build a team to reflect "Ozzie Ball", they still seem to gravitate towards the long ball. As it stands, their 26 team home runs is currently second behind the Blue Jays (28) but the majority of bombs have been of the solo variety. Still, while Twins fans worry over clutch and timely hitting, the White Sox are mired with a .143 average with runners in scoring position in the past 10 games to go along with their baseball worst .222 overall batting average. 
• Ozzie Guillen believes that Sergio Santos, former Twins farmhand turned reliever in the White Sox organization, has the chance of being the team's closer someday. 
• ANALYSIS: The "salvage" project has yet to allow a run in 8 innings of work. Thus far, he's been one of the dirtiest relievers in the game - his 57.5% contact rate is the fourth-lowest among relievers in all of baseball. Santos is hitting 95.5-mph on average and supplements that with a slider/changeup combination that has worked very well for the 26-year-old. Armed with those three plus pitches, Santos could easily usurp the incumbent closer Bobby Jenks who is eligible for his final year of arbitration in 2011. Although there are discussions regarding Santos transitioning to a starter's role, the righty has little designs on moving from the back-end of the bullpen where he prefers to remain. 
• With a .355 OPS, catcher AJ Pierzynski remains one of baseball's least productive players in the early going of the 2010 season. In his past 25 at-bats, Pierzynski has coax just a solitary hit off of Tampa's David Price a week ago Tuesday. 
• ANALYSIS: The 33-year-old catcher seems to be the recipiant of some horrendous luck. While putting the ball into play regularly on line drives similar to his career rate (21.2% LD%), Pierzynski hasn't had many fall in for hits as his .154 BABIP is the fourth-lowest in baseball. These two numbers would be indicative of a impending turnaround. Never one to walk or strikeout much, Pierzynski has been seeing an extremely high percentage of fastballs (71% FB) but has failed to hit them solidly (.140 well-hit average versus a .204 league-average).  

Cleveland Indians | 8-11 T-3rd | 5 games back

• On Monday night, the Indians were 1-for-11 with runners in scoring position and left 14 men on base in the 5-2 loss to Anaheim. 
• ANALYSIS: While no one really anticipated much from this lineup, with Grady Sizemore returning after an injury-riddled 2009 season, there was optimism that the young team would be able to improve. Currently, the Indians exercise baseball's worst average in baseball (.223), the worst RISP average (.205) and, unlike the White Sox who have compensated with the long ball, Cleveland's 14 home runs is tied for third fewest in baseball. All of this has led to just 62 runs scored - tied with Baltimore for the fewest in the American League. 
• After throwing in a simulated game in Oakland, injured closer Kerry Wood is gearing up for his rehab assignment. "I don't know how long it will take," said Wood. "At this point I'm not putting any number of days on it. I'm just going to go and come back when it feels ready to go."
• ANALYSIS: Wood's simulated game didn't go so well. The Cleveland Plain Dealer reports that he was unhappy with his performance and that it may signal a significant step back in his return to the majors. Interim closer Chris Perez has been 4-for-5 in his save opportunities in Wood's absence but is fairly raw in his abilities. Though he might be the closer of the future, his nasty 3/6 K/BB ratio is far from the closer echelon and he has fallen behind hitters far too frequently (40.6% first-pitch strike). The Indians need to get Wood back on the field in order for him to make a few appearances to inflate his trade value enough to unload his massive contractual obligations on some other unsuspecting team. 

Detroit Tigers | 11-9 2nd | 2.5 games back

• After his first four starts, Justin Verlander is 1-1 with a 6.95 ERA and 19 strike outs in 22 innings pitched. 
• ANALYSIS: Starting out slow is nothing new for Verlander. Last year through his first four starts the hard-throwing righty was 0-2 with a 9.00 ERA. The year before that? In '08 he started 0-3 with a 7.03 ERA. In general, Bill James found that power pitchers struggle a bit more at the beginning month of the season so Verlander should turn it around quickly. At the same time, Verlander did log 240 innings (most in MLB) and threw over 120 pitch in 11 of his outings while averaging 112 pitches per game. It is quite possible that there will be signs of toll on his arm in '10. Verlander's fifth start doesn't get any easieras he faced the Twins: Thome, Morneau and Mauer are a combined 33-for-108 (.305) with 12 HRs.  
• Like Verlander, sophomore starter Rick Porcello is also in the midst of a rough patch in the season's opening month. Through four starts, Porcello is 1-2 with a 7.91 ERA and 13 strikeouts in 19.1 innings of work.
• ANALYSIS: Porcello's actually thrown very well. He's getting ahead of hitters (58.7% first-pitch strike) and getting more groundballs (56.3% GB) while avoiding solid contact (12.7% LD rate down from 17.1% in '09). So what's the youngster's problem? His .449 BABIP is weighing him down (the highest in the AL). Behind him, the defense is failing to convert balls in play into outs -- especially his grounders. Opponents have a .415 BABIP on earth-scorchers when the league average has been at a .207 BABIP. With his strong batted ball numbers, his BABIP should begin to equalize over the next four starts. 

Kansas City Royals | 8-11 T-3rd | 5 games back

• Following Sunday's 4-3 win over the Twins, manager Trey Hillman was asked if the combination of Dusty Hughes, Josh Rupe and Joakim Soria was the right combination to ensure protect leads. Hillman replied no and said that lefty John Parrish, who allowed a game-tying home run to Justin Morneau on Saturday night, has one of the best lefty-on-lefty breaking balls among his internal options. 
• ANALYSIS: The bullpen has been atrocious, that's for sure. Their 6.38 ERA is the worst in the American League by almost a run. While the personnel hasn't been elite for Hillman, part of the blame rests squarely on his shoulders. A quick check of the numbers reveals that Hillman's statement isn't quite true. Left-handed opponents are hitting just .125/.333/.125 with a .250 well-hit average off of his breaking stuff while Parrish's breaking stuff has been thwacked to the tune of .375/.500/.750 with a .375 well-hit average. 
• The Royals claimed Jai Miller who was released from the Oakland Athletics organization.
• ANALYSIS: The right-handed hitting Miller is an extremely strikeout-prone hitter (237 in 884 plate appearances since '08) that has some pop (35 HR the past two seasons). While he is a .236/.320/.386 career minor league hitter, he has hit .270/.347/.473 in AAA. He's an insurance policy in the event that Rick Ankiel is unable to recover quickly and will likely fill out Omaha's roster. 

Time to shave the beard?

As the rest of the Twins lineup is busy producing runs like a taco stand serving tainted meat, Jason Kubel has been inauspiciously quiet. Since the home opener the left-handed slugger has had fewer hits than Chumbawamba, going just 3-for-29 (.103) with nine strikeouts.

On Wednesday, I showed that part of the reason for his slump is because pitchers have noted his insatiable appetite for meaty fastballs and have switched his diet to low-fat and tasteless sliders and curves. The results are fewer pitches in the strike zone and ultimately fewer pitches he can feast upon. Kubel has displayed restraint in most cases – drawing more walks and chases after out-of-zone pitches less – by largely ignoring the servings of non-fastballs and off-the-plate appetizers. 

Yet in order to stop his batting average from slinking towards a number typically reserved for describing a Brewers fan’s blood alcohol content, Kubel also needs to stop hitting them directly at people. There are signs that the defense's good fortunes might not last much longer. For one thing, is batting average on balls in play (or BABIP for shorthand) is absurdly low. As a rule of thumb, if this number is well-below or towers above the league average, there is a strong indication that a player is primed for improvement or regression. In Kubel’s case, the lefty is sporting a BABIP (.226) as ugly as his beard – and far below the league average (.291) in addition to his own career mark (.303). 

Meanwhile, considering the method in which he is putting the balls into play, we can easily deduce that he is hitting the ball square. In Kubel’s 56 plate appearances before Thursday’s game, he has hit 27% of his balls in play as line drives. This is an extremely positive total. In general, line drives fall in for hits far more often than grounders or fly balls. Last season, liners became hits 72% of the time while grounders did so 24% of the time and fly balls just 13.4% (with the exception of home runs which are not considered “in play”). The natural conclusion is that if his line drive totals are up, the batting average will eventually correct itself as line drives find vacant real estate. 

But not only is he hitting line drives regularly, he’s hitting everything solid. Behind Inside Edge’s pay wall is a fairly underutilized statistic that may assist in bridging the gap from the “assumed” (i.e. high line drive rate coupled with low BABIP equals bad luck) to the “actual” (i.e. genuinely screaming balls around the field off his bat). Like Baseball Info Solutions, who gathers all of the batted ball data that we find at Fangraphs.com, Inside Edge has added a little extra flavor by denoting if the ball – be it grounder, liner or fly ball - was well-hit. The Well-Hit Average (well-hit balls/at bats) provides us with another metric to gauge the type of contact, regardless if it was hit land, air or sea. While the rest of the league holds a .208 well-hit average, Kubel has exercised a very good .239 well-hit average. 

If he continues to spray shots around the ballyard at the same rate, there is no reason not to expect a full turnaround long before summer begins. 

However, if this decline continues on the road trip, the next step is to shave the beard. 

Give the man a fastball

Jason Kubel has entered some early season doldrums. In the past four games, Kubel is just 1-for-16 with four strikeouts. His overall totals are even less affirming. In the first 14 games, Kubel has buoyed a sad-looking .205/.327/.364 batting line with two home runs in 52 plate appearances. While he’s showing more patience, walking 8 times (15.4% BB%), he’s also striking out more (25% K%) and has lost some overall pop (.159 isolated power down from .239 in ’09). Admittedly, Kubel’s line drive rate is very attractive (27.3% LD%) but this downturn is quite the contrast from a year ago in which the lefty marched through opponents’ pitching staffs on a mission.

 

Opposing teams made a shrewd observation based on his performance last year: Kubel was absolutely shredding fastballs. Ostensibly, pitchers respected Kubel’s ownership of the fastball and curbed their deployment of fastballs accordingly in ’09, throwing them just 53.3% of the time. Nevertheless, he turned pitcher’s high cheddar into minced meat, slugging .667 on fastballs resulting in a 27.2 run above average (11th-best in baseball). The harder you threw it, the harder he hit it.

 

The general strategy for defusing Kubel this year has been “If he’s going to feast on the heat, let’s feed him less of it.” Now, Kubel receives a fastball about as often as Halley’s Comet visits this rock. So far in 2010, Kubel has seen the lowest mix of fastballs in baseball:

 

Kubel and the Heat:	2009	2010
Fastball%	53.3	41.8
Slugging% on FB	.667	.350
wFB	27.2	-1.3

 

Being the recipient of a high dosage of breaking pitches has in turned increased the number of balls out of the zone. Whereas in 2009, pitchers went into the zone 47.1% of the time, he’s getting just 43% of pitches faced in the strike zone (well below the 48.6% league average). This has naturally led to fewer balls that he can drive thus the decline in his isolated power.

 

Because of this, Kubel will have to make some adjustments to his approach. There are already signs that he is doing just that. Seeing that his walk rate is up and that he is chasing fewer pitches out of the zone (20% chase%) demonstrates that he is capable of being selective and waiting for his pitch (i.e. the occasional fastball). If he continues to put the ball in play on a line like he has been doing, there is no doubt that his average will rebound as some of those batted balls begin to fall in for hits.

Off-Day Happenings.

Monday's scheduled off-day will give Twins fans a night free of baseball to enjoy the unusually warm spring evening in Minnesota. However, if you are an agoraphobic, 1500ESPN's Phil Mackey has you covered. He's organized a live chat on-line to discuss the state-of-the-Twins for tonight at 8 PM. Joining Mackey will be Aaron Gleeman, John Bonnes, Seth Stohs and myself, screeding away thoughts and opinions on the team's 9-4 start. That's right: Four iconic Twins writers and me, the Ringo Starr/Oates/Garfunkel of the blogging community. 

Other matters:

• The Twins' new stadium is keeping MLB's attendance numbers from going kerplunk. The turnout thus far has been wonderful yet it appears that the interest in the mid-week games against Cleveland are not drawing nearly the same attention that the Boston series did.
• Justin Morneau's 13 walks is tied for the most in the American League. Part of the reason is that pitcher's are refusing to throw Morneau strikes, hitting the zone just 41% of the time (below the 48% average) and Morneau, in turn, is not chasing those pitches as much as he had in the past (following just 25% of pitches out-of-zone). Speaking of walks, the Twins are currently tied with the Braves for the most in baseball (65). 
• The Twins offense has had 36 of their plate appearances run to 3-0 counts. That's seven more than the next closest, the Detroit Tigers. 
• Ron Gardenhire is certainly picking the right moments to use Jim Thome's bat off the bench as Thome's pinch hitter leverage is at 2.59 - the 7th-highest in baseball. Unfortunately the big man is just 1-for-5 in his opportunities.
• Target Field is playing well for Orlando Hudson. After a slow start on the road since the inaugural game in the new outdoor stadium, Hudson is 7-for-22 (.318) with three extra base hits, six walks and six runs scored. 
• According to BillJamesOnline.net, the Twins are second in the American League in net bases gained with +11, trailing the go-go Oakland A's who are +24 bases and leading all of baseball. 
• John Dewan's Plus/Minus defensive system currently pegs Nick Punto (+4) tied with Jose Lopez, Miguel Tejada and Ian Stewart as the top third baseman in baseball. Despite what Dick N Bert like to relay during the telecasts, Denard Span ranks 30th among center fielders with a -1 rating, losing most of his marks in fielding deep fly balls. 
• Baseball America's JJ Cooper reviews prospect Kyle Gibson's first two professional starts. After a five-run, six-hit debut that included a pair of home runs, Miricles pitching coach Steven Mintz said that Gibson's outing was a little misleading given the stiff wind that day. His second outing demostrated Gibson's talent better, as the 2009 first round draft pick implemented a solid changeup to keep hitters off-balance.
