Lefty Bruce Chen has announced on Twitter that he will retire from professional baseball. Chen, 37, was designated for assignment by the Indians on Saturday.

Chen struggled through 6 1/3 innings in two starts this year for Cleveland, permitting nine earned runs. He struck out four and walked one batter, but gave up 17 total hits — including three long balls.

Of course, Chen has long provided plenty of innings and flexibility to 11 total MLB clubs. The wily southpaw never relied much on velocity, working in the mid-80s in recent seasons. But that didn’t stop him from compiling over 1,500 innings in the majors.

All said, the Panamanian native compiled a 4.62 ERA with 6.7 K/9 against 3.2 BB/9 over 17 big league campaigns. Chen broke into the big leagues with the Braves at age 21. Atlanta signed him as an amateur way back in 1993.

Chen is, perhaps, most associated with the Royals, with whom he spent six seasons. His time in K.C. represented something of a late-career renaissance, as he compiled 5.6 rWAR in that span (in spite of a rough final campaign).

The Orioles arguably enjoyed Chen’s most productive overall campaign in 2005, when he racked up a career-high 197 1/3 frames while working to a 3.83 ERA. He ultimately spent three years with Baltimore, with his 343 2/3 innings with the O’s representing the second-most he logged with any single team.
