Corey Kluber, who pitched for 13 seasons across five MLB teams including the Red Sox last year, announced his retirement from baseball on Instagram Friday.

“A special acknowledgment to the Cleveland Guardians, Texas Rangers, New York Yankees, Tampa Bay Rays, and the Boston Red Sox for granting me the privilege of wearing their jerseys and being a part of your teams,” Kluber wrote in a slide on his Instagram post.

“Each chapter was filled with priceless experiences, phenomenal teammates, and the backing of devoted fans, whose steadfast support always moved me to be the very best I could every time I toed the rubber.
