The 2013 World Series Champion, Boston Red Sox, exercised their option on left-handed pitcher Jon Lester for $13 million dollars.

Lester, who turns 30 in January, was 15-8 with a 3.75 earned run average in 33 starts in the regular season. He was then 4-1 with a 1.56 ERA in five postseason starts, going 34.3 innings.

Lester won both games he started in the World Series, allowing one run over 15.1 innings.

Lester is 100-56 with a 3.76 ERA in 221 career regular season appearances since 2006. His 1,237 career strikeouts are the most ever by a Red Sox left-hander and fifth overall in franchise history.

Think Lester was happy?
