A Cy Young Award winner and three-time All-Star, Peavy, 32, has gone 8-4 with a 4.28 ERA (38 ER/80.0 IP) in 13 starts this season for the White Sox. He has compiled 76 strikeouts compared to 17 walks in 2013 for a 4.5 strikeout to walk ratio, which entered today as the sixth-highest mark among all American League pitchers with at least 80.0 innings.
Peavy, who has thrown 6.0 or more innings in 10 of his 13 outings this season, spent time on the disabled list this year with a fracture of his left fourth anterior rib. He has won both of his starts since being activated on July 19, victories over the Atlanta Braves on July 20 and Detroit Tigers on July 25.
The Mobile, AL native, who began his career with the San Diego Padres in 2002, was the unanimous National League Cy Young Award winner in 2007 after he led the majors in both ERA (2.54) and strikeouts (240).
Peavy also led the majors in ERA in 2004 (2.27), his second full big league season with San Diego. He is that franchise's all-time leader in strikeouts (1,348), and ranks in the top five in several other Padres career pitching categories including wins (T-2nd, 92), winning percentage (2nd, .575), starts (3rd, 212), and innings (4th, 1,342.2).
In 45 starts since the beginning of 2012, Peavy has won 19 games and owns a 3.61 ERA. With Chicago last season, he ranked ninth among AL qualifiers with a 3.37 ERA and was named an All-Star for the third time in his career. He also placed among 2012 AL leaders in innings (5th, 219.0), opponent batting average (5th, .234), and strikeouts (8th, 194), and earned his first career Rawlings Gold Glove Award.
A 12-year major league veteran, Peavy was originally a 15th-round selection of the Padres in the 1999 June Draft. Over his career, he has a record of 128-97 with a 3.49 ERA (730 ER/1880.1 IP) in 296 big league games (295 starts) between the Padres (2002-09) and White Sox (2009-13). Peavy's 1,824 career strikeouts rank 11th among active major leaguers.
Peavy's career average of 8.7 strikeouts per nine innings pitched entered Tuesday as the second-best mark among active pitchers with at least 1,500 career innings, trailing only Johan Santana (8.8). He ranked third among actives with a .235 opponent batting average and fifth with a 1.18 WHIP.
The 26-year-old Villarreal, a native of La Guaira, Venezuela, has fanned 86 batters in 75.0 career major league innings, all in relief with the Tigers over the past three seasons beginning in 2011.
