The Red Sox on Friday exercised their $13 million contract option on lefthander Jon Lester for the 2014 season.

Lester, who turns 30 in January, was 15-8 with a 3.75 earned run average in 33 starts during the regular season.

He was then 4-1 with a 1.56 ERA in five postseason starts, going 34⅔ innings.

Lester won both games he started in the World Series, allowing one run over 15⅓ innings while striking out 15 and surrendering one walk.

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 lefthander and fifth overall in franchise history.


Lester has started 194 games the last six seasons. Only 10 starters in the majors have more. Detroit righthander and 2011 AL Cy Young winner Justin Verlander has the most over that time with 202.

Picking up the option does not preclude the Red Sox and Lester from working out a multiyear contract that would start in 2015.

The team faced a Saturday deadline to pick up or decline the option.

Talks on an extension have not started.

The Red Sox also have a $6 million option on lefthanded reliever Matt Thornton that they are expected to decline.

Thornton appeared in only 20 games for the Red Sox after being obtained from the Chicago White Sox on July 13. He went 0-1 with a 3.52 ERA, five walks, and nine strikeouts over 15⅓ innings.

He was not on their roster for any round of the postseason.

Dustin Pedroia, who tore a ligament in his left thumb on Opening Day, said on WEEI that he would have surgery “probably in a couple of weeks” once he gets an MRI.

Pedroia was injured sliding headfirst into first base. The injury sapped his power for much of the season.


Pedroia’s .415 slugging percentage was the lowest of his career and he hit nine home runs over 641 at-bats, his fewest since 2007 when he hit eight over 520 at-bats.

Aruba is rallying behind Xander Bogaerts, the first player from that country to play in the World Series.

“Congratulations for making every single Aruban proud. Regardless of our own personal team preferences, we are now all Boston Strong filled with Aruban pride,” Aruba Minister of Tourism Otmar Oduber said in a statement.

Winning another World Series didn’t automatically make the Red Sox favorites to repeat next year.

Oddsmakers in Las Vegas sports books like the Los Angeles Dodgers to win it all in 2014, with most books making them an 8-1 pick for the title.

At the Wynn hotel-casino the Detroit Tigers are next at 9-1, followed by the Red Sox at 10-1.

Those looking for a real long shot need look no further than Houston; the Astros are as much as 250-1 to win it all. Minnesota and Miami are next at 125-1.
