Twins relief pitcher Tyler Duffey was ejected from Tuesday's game against the White Sox after he threw a pitch behind Yermín Mercedes's legs.
In the seventh inning, with the White Sox up 4-2, Duffey threw the pitch behind Mercedes and he was subsequently tossed along with Twins manager Rocco Baldelli, who argued with umpire Jim Reynolds. Bill Evers stepped in to serve as the acting manager for the remainder of the game after Baldelli's exit.
Before Duffey's ejection, he did not have any prior pitching issues in the game.
On Monday, Mercedes blasted a home run on a 3-0 pitch despite the White Sox's sizable lead over the Twins—breaking one of MLB's unwritten rules.
