The Boston Red Sox have exercised their $13 million option on the contract of Clay Buchholz for 2016.

Buchholz, 31, was 7-7 with a 3.26 ERA in 18 starts this year, striking out 107 and walking 23 in 113 1/3 innings.

His season was cut short by a strained right elbow that caused him to go on the disabled list on July 11.
