Longtime major league outfielder Kole Calhoun is retiring, he announced Friday night via Instagram.

"The day has come that I announce my retirement from Major League Baseball," Calhoun, 36, began his post. "I know how extremely lucky I am to even be able to say that. Baseball was always my dream, and to make that my reality fills me with gratitude.

"I have loved this game since I can remember so making this announcement weighs heavy on my heart. This day comes for all players eventually and I can honestly say that I have given this game everything I have and I walk away with no regrets."

Josh Donaldson, who won the American League MVP during a 13-year career, announced his retirement Monday.

Donaldson, 38, made the announcement on the podcast of former player Sean Casey.

Donaldson finishes his career with 279 home runs, 1,310 hits and a long-earned reputation as a someone who competed with an edge, unafraid of offending opponents. He had his best season in 2015 with Toronto, when he hit 41 homers and drove in a league-high 123 runs, while scoring an MLB-high 122 runs. Donaldson received 23 of 30 first-place votes for the MVP, finishing ahead of Mike Trout for the award.
