Gardenhire joined Mauer at the plate to argue the call, but both walked back to the dugout after being told the call would not be changed and that it wasn't reviewable. But Gardenhire was thrown out from the dugout for continuing to argue with Segal, as he wanted the ball to be checked for any marks coming from the foul tip or the dirt.
"It was a situation where we thought the ball hit the dirt and was a foul ball," said Twins bench coach Terry Steinbach, who filled in for Gardenhire as manager. "Joe is a great hitter and tracks the ball really well and doesn't complain. So that was our first indication.
"Gardy went out there to try to argue it. Fieldin [Culbreth] came in from third and said from the best he could tell it didn't hit it. And then the ejection came when we asked them to check the ball and Chris wouldn't do it."
It marked the fifth time this season that Gardenhire was tossed. He leads all active managers with 72 career ejections.
