Tigers’ Carpenter Aggravates Heel Injury Amid Equipment Transition

Detroit Tigers right fielder Kerry Carpenter exited Sunday’s 5-4 loss to the Kansas City Royals in the fifth inning after reaggravating a bruised left heel. Manager A.J. Hinch confirmed the issue is the same one that has bothered the outfielder over the past week, requiring a re-evaluation following the game. Carpenter went 0-for-2 before being replaced by Ben Malgeri.

The injury flare-up occurred during a fourth-inning at-bat, impacting the mechanics of Carpenter’s swing. As a power hitter, he relies heavily on loading his weight onto his left foot—his plant leg—while keeping his right foot airborne. The bruising on the heel compromises this foundation, causing issues that were initially limited to running but have now begun to affect his performance at the plate.

Carpenter attributes the physical problem to a recent switch in footwear. The five-year veteran revealed that his previous model, manufactured by Under Armour, Inc., was discontinued after seven years of use. He transitioned to New Balance cleats to find a suitable replacement, but the new shoes featured an extra spike under the heel. While equipment managers removed the additional stud on Wednesday, the underlying soreness has persisted.

On the field, the injury coincides with a difficult stretch for Carpenter. Through 80 games in the 2026 season, he is batting .210 with 13 home runs and a .698 OPS. His production has declined further since July 1, recording a .120 average with zero home runs and RBIs over his last 50 at-bats.

Under Armour shares recently closed at $7.03, representing a 4.3% increase for the session. The company specializes in performance footwear and apparel across the sports industry.
