One of baseball’s longest tenured players may be nearing the end of his career. The Atlanta Braves designated 20-year veteran Bartolo Colon for assignment on Thursday.

The news is certainly not surprising. Colon has been ineffective throughout 2017, posting an 8.14 ERA and 1.778 WHIP in his first year with Atlanta. At 44, it’s highly possible that Colon has thrown his last pitch.

Colon broke into MLB in 1997 with the Cleveland Indians. He’s subsequently pitched for the Montreal Expos, Chicago White Sox (twice), Los Angeles Angels, Boston Red Sox, New York Yankees, Oakland Athletics, New York Mets, and finally the Braves.

His career highlights include being a four-time All-Star (including as recently as 2016) and winning the American League Cy Young in 2005 with the Angels. Additionally, with the 2016 retirement of Maicer Izturis, Colon became the last active MLB player to have played with the Montreal Expos.
