Liriano helped pitch the Pirates to their first postseason berth since 1992 by going 16-8 with a 3.02 ERA and racking up 166 strikeouts in 161 innings. He overcame a disastrous 2012 campaign in which he posted a 5.34 ERA while walking five batters per nine innings for the Minnesota Twins and Chicago White Sox.
2013 marks the second time Liriano has won a Comeback Player of the Year award. He was the American League's winner in 2010, when he went 14-10 with a 3.62 ERA and surrendered a league-low 0.4 home runs per nine innings after struggling to a 5-13 record and 5.80 ERA in 2009.
Liriano is the first Pirates player ever to win the award, which was implemented before the 2005 season.
