This left-hander mustered only 10 wins for Toronto in 2017, 10 fewer than his career high in 2016. 2017 was more in line with expectations, since he had never won more than 12 games in a season before his 2016 run, which earned him only a 6th place finish in the AL Cy Young vote.
Name this starting pitcher whose career high before 2016 was 12 wins for the 2009 Philadelphia Phillies.
J.A. Happ
