It’s at least twelve hours of baseball today as all four series are scheduled for Friday. The action starts at noon EDT with the Tigers and Orioles playing game two of their ALDS series. Justin Verlander faces Wei-Yin Chen. Verlander lost some power this season, with just 159 strikeouts in 206 innings. It was the first time since his 2006 rookie season that he allowed more hits than innings pitched. He did finish with two strong starts, however, allowing two runs and no walks in 15 1/3 innings, striking out ten. Chen lowered his ERA half a run compared to his first two seasons with the Orioles, good for a 16=6 record. He figured out how to keep the ball in the park in the second half, allowing just six home runs after the All-Star break in 81 2/3 innings after giving up 17 HR in 104 innings before the break.
The Giants and Nationals begin their NLDS series at 3 PM EDT with Jake Peavy battling Stephen Strasburg. Peavy turned his season around after joining the Giants cutting both his walk and home runs rates compared to pitching for the Red Sox. This wasn’t a home park effect per se, as Peavy pitched worse on the road with Boston this season. Strasbrug posted great strikeout and walk rates, but was susceptible to the home run. He was especially effective at home, with a 2.56 ERA, walking 18 and striking out 140 in 116 innings. He was extremely strong in September, 3-1 with a 1.13 ERA in five starts, with just one home run allowed.
The best pitching match-up of the day takes place at Dodger Stadium with Adam Wainwright facing Clayton Kershaw. Since 2009, Kershaw and Wainwright are 1-2 in the National League in ERA, Kershaw at 2.33, Wainwright at 2.83. (The linked list is the major league leaders with at least 800 innings. Of the top 20, 11 are in the playoffs this year, and there would have been 12 if Matt Cain were healthy. It even works better as the top 23 contain 14 pitchers in the playoffs.) In that time Kershaw wins strikeouts by a wide margin, Wainwright is better at preventing walks, and they are about even at preventing home runs. Clayton owns a 93-44 record, Wainwright 92-50. Note that Wainwright missed all of the 2011 season.
Finally, the Royals try to make it two games in row over the Angels as Yordano Ventura takes on Matt Shoemaker. Ventura did pitch in relief on Tuesday getting one out and giving up two runs. He had a reverse platoon advantage this year, pitching better against left-handed batters. Ventura held them to a .232/.299/.343 slash line. Shoemaker found his groove in late July, posting a 1.49 ERA over his last 11 appearances. He allowed just three home runs in those 66 2/3 innings.
Enjoy!
