The Philadelphia Phillies have acquired former top catching prospect Carter Kieboom from the Cleveland Guardians in a minor league deal. Kieboom, a 28-year-old catcher, will report to the Phillies' Triple-A affiliate and provide additional depth behind the plate for the organization.

Why it matters

The Phillies are World Series contenders this season, and while they didn't make many major roster moves this offseason, this trade adds an intriguing piece to their catching depth chart as they prepare for the upcoming campaign.

The details

Kieboom, a former top prospect of the Washington Nationals, has struggled to find success at the major league level, posting a .597 OPS in 450 at-bats over five MLB seasons. However, he had a solid 2025 minor league season, batting .319 with 9 home runs, 57 RBIs and an .817 OPS in 370 at-bats. The Phillies are acquiring Kieboom for cash considerations and will assign him to their Triple-A roster, where he will serve as organizational depth behind major league catchers Rafael Marchan and Garrett Stubbs.

  • The trade was reported on March 21, 2026, just before the start of the MLB season.
