World Series champion pitcher Andrew Heaney has retired from MLB after 12 seasons, he announced in an Instagram post Sunday.

Heaney, 34, said playing in MLB “has been a unique honor and privilege.”

“But I am now ready to return my focus and energy to being a husband, father, family man, and active member of my community,” Heaney wrote. “I’m retiring from baseball, but I hope to give back more than I received. Thank you to all of you for the love and support you have given me. Y’all know who you are.”

Heaney helped lead the Texas Rangers to winning the 2023 World Series, earning the win in Game 4 of the five-game series with one run allowed in five innings pitched against the Arizona Diamondbacks.

Most recently, the southpaw pitcher spent the 2025 MLB season with the Pittsburgh Pirates and Los Angeles Dodgers. He also previously pitched for the New York Yankees, Los Angeles Angels, and Miami Marlins, the latter of which drafted him in the first round of the 2012 MLB Draft.

“I played with many of the greatest players of this generation and potentially some of the best players to ever wear a uniform,” Heaney wrote in his Instagram post. “I’m humbled that I was even able to share the field with them. I was never an All-Star and definitely not a Hall of Famer, so I can only hope that I was great to each fan, player, coach, and staff member I got to be around.”

Heaney finishes his MLB career with a 56-72 record in 230 games, including 208 starts, along with a 4.57 ERA, 1.28 WHIP and 1,156 strikeouts in 1,136.2 innings pitched.
