Right-hander Ryan Dempster, who sat out the 2014 season due to physical issues and a desire to spend more time with his family, will not pursue a contract this offseason and will officially retire, reports Chris Cotillo of SB Nation’s MLB Daily Dish (on Twitter).

The 37-year-old Dempster was placed on the restricted list by the Red Sox following that decision, meaning that he forewent a sizable $13.25MM salary. At the time, Dempster told FOX’s Ken Rosenthal, “I don’t feel like I am capable of performing to the ability and standard that I am accustomed to. I feel it’s in the best interest of both the club but most importantly myself to step away from playing baseball at this time.” Over the summer, Dempster told the Chicago Tribune that he wasn’t ruling out a return to the playing field, but he didn’t miss playing at that point.

Dempster’s career will come to a close with a 4.35 ERA, 7.8 K/9 and 4.0 BB/9 in 2387 Major League innings. The former third-round pick and British Columbia native experienced success both as a starter and as a reliever in his career. He made 351 big league starts and totaled 132 Major League victories, but he also spent three seasons as the Cubs’ closer and totaled 87 saves in his career.

The final season of Dempster’s career certainly wasn’t his finest, but it may be his fondest memory. Dempster posted a 4.57 ERA in 171 1/3 innings for the Red Sox that season and was rewarded with a 2013 World Series ring when all was said and done.

A two-time All-Star, Dempster also finished sixth in the 2008 National League Cy Young voting in a surprisingly dominant campaign as he transitioned from the bullpen back to the rotation. He totaled 206 2/3 innings that season, posting a 2.96 ERA and averaging 8.1 strikeouts per nine innings along the way.

Baseball-Reference.com values Dempster’s career at 22.6 wins above replacement, while Fangraphs pegs him at 27.5 WAR. In parts of 16 Major League seasons with the Marlins, Reds, Cubs, Rangers and Red Sox, Dempster earned more than $89MM, according to B-Ref. We at MLBTR wish Dempster the best of luck in his post-playing days.
