Two-time American League Cy Young Award winner Corey Kluber announced his retirement on social media Friday morning, ending a 13-year career.

A three-time All-Star, Kluber won his first Cy Young with Cleveland in 2014 after going 18-9 with a 2.44 ERA. He won the award again in 2017, finishing 18-4 with a 2.25 ERA.

Kluber, 37, finishes with a 116-77 record and a 3.44 ERA in 271 career games, all but 11 as a starter.

"With sincere appreciation, I am announcing my retirement from Major League Baseball, concluding a remarkable 13-season Major League Baseball journey," Kluber posted on Instagram. "I am deeply grateful for the support of numerous individuals and entities that profoundly influenced my path."

The right-hander pitched for the Boston Red Sox last season, going 3-6 with a 7.04 ERA in 15 games, including nine starts. He had signed a one-year, $10 million contract with Boston for the 2023 season that included an $11 million club option for 2024, but the Red Sox declined to pick that up in November.

Kluber went 5-3 with a 3.83 ERA in 16 starts for the New York Yankees in 2021, including a no-hitter in a 2-0 victory at Texas. He pitched for the Tampa Bay Rays in 2022, going 10-10 with a 4.34 ERA in 31 starts.
