Home plate umpire John Tumpane approached Detroit Tigers right-hander Casey Mize and catcher Jake Rogers after the first inning for a conversation.
Manager AJ Hinch exited the dugout to join them.
For the second inning, Mize returned to the mound with Kyle Funkhouser's glove. It's unclear why Mize switched gloves, but it seemed like Tumpane told him to make a change. (MLB announced Tuesday pitchers caught using foreign substances will be given an automatic 10-game suspension, beginning June 21. Starting pitchers will be checked more than once per game.)
Even without his main glove, Mize used Funkhouser's leather to lead the Tigers (28-39) to a 4-3 win over the Kansas City Royals at Kauffman Stadium.
