Liriano could hold key for Pirates in wild-card game
Francisco Liriano had the best single season against left-handed hitters in major league history.
Yes, the best in baseball history.
Using the Baseball-Reference Play Index, Grantland.com found Liriano's .321 opponent on-base-plus-slugging-percentage mark against left-handed hitters was the best of all-time among left-handed pitchers who have faced a minimum of 100 left-handed batters in a season.
That dominance is good news for the Pirates in Tuesday's wild-card game against the Reds. The Reds' three best hitters — Shin-Soo Choo, Joey Votto and Jay Bruce — are left-handed. And it is Liriano, the Pirates' starter, versus those left-handed hitters that could determine which team advances to the National League Division Series.
Choo, Votto and Bruce are impact hitters. But each is significantly less effective against left-handed pitching.
Choo batted about 100 points worse against lefties (.215) than righties (.317). Votto has an .824 OPS vs. left-handers and a .977 mark against righties. Bruce is 0 for 11 against Liriano in his career.
Why has Liriano been so dominant against left-handed pitching?
“When he gets strike one against a lefty, he's got multiple different weapons to go to,” Pirates manager Clint Hurdle said. “Everything is coming out of the same arm slot: that dynamite slider, his parachute changeup and a good two-seam fastball.”
Liriano (16-8, 3.02 ERA) always has had a swing-and-miss slider and changeup, but he improved his fastball command in going to a two-seamer this season. It's a major reason he is having his best year since his rookie season.
