Early Life and education

Mitch Keller is now 29 years old and was born on April 4, 1996, in Cedar Rapids, Iowa to parents, Al Keller and Joni Keller and has a brother named Jon.

He attended Xavier High School in his hometown, where he excelled on the mound and was rated among the nation’s top high school pitchers.

Initially committed to play college baseball at the University of North Carolina, he opted instead to sign with the Pirates after they selected him in the second round of the 2014 MLB Draft, foregoing his collegiate plans.

Personal Life

Mitch Keller married his longtime partner Clancy in 2020, and together they have a son named Quinton Keller (born January 22, 2025).

His brother, Jon Keller, spent time in the Baltimore Orioles’ minor league system but did not reach the majors.

Outside of baseball, Mitch keeps his family life relatively private and has no additional publicly disclosed children beyond his son, Quinton.

Career

After signing for a $1 million bonus in June 2014, Keller progressed steadily through the Pirates’ farm system.

He debuted professionally with the Gulf Coast League Pirates in 2014 and advanced to Triple-A Indianapolis by mid-2018, where he was named International League Pitcher of the Year following a 3.56 ERA over the season.

Promoted to the majors on May 27, 2019, he allowed six earned runs in his debut but secured a rotation spot by August.

In 2021, a midseason demotion to Triple-A helped him refine his command; upon returning, he closed out the campaign with improved performances.

The 2022 season saw Keller perfect a new sinker, yielding a 3.91 ERA and logging 138 strikeouts over 159 innings, including surrendering Albert Pujols’s 703rd and final career home run on October 4, 2022.

Keller’s breakout came in 2023: he was named Opening Day starter, tossed his first complete-game shutout on May 9, and earned National League Player of the Week honors before being selected to his first All-Star Game on July 2, 2023.

He finished with a 13–9 record, a 4.21 ERA, and a career-high 210 strikeouts.

On February 22, 2024, he signed a five-year, $77 million extension, again drawing the Opening Day assignment.

As of July 8, 2025, Keller’s career MLB record stands at 39–60 with a 4.45 ERA and 776 strikeouts.
