Former Red Sox pitcher Lester announces retirement
CHICAGO — Jon Lester, a durable left-hander who won three World Series titles during 16 years in the majors, has announced his retirement.
Lester, who turned 38 on Friday, finishes with a 200-117 record and a 3.66 ERA in 452 career games, including 451 starts. He also has been a reliable postseason performer, compiling a 2.51 ERA in 26 appearances.
The 6-foot-4 Lester helped Boston win the championship in 2007 and 2013, and led the Chicago Cubs to the title in 2016. The championship for the Cubs was the franchise’s first since 1908.
“It’s kind of run its course,” Lester told ESPN. “It’s getting harder for me physically. The little things that come up throughout the year turned into bigger things that hinder your performance.
“I’d like to think I’m a halfway decent self-evaluator. I don’t want someone else telling me I can’t do this anymore. I want to be able to hand my jersey over and say, ‘Thank you, it’s been fun.’ That’s probably the biggest deciding factor.”
