Morneau might have inner-ear infection

First baseman leaves Monday's game with dizziness

ARLINGTON -- Twins first baseman Justin Morneau left Monday's 8-5 loss to the Rangers in the fourth inning after experiencing dizziness.

The Twins said that Morneau was removed from the contest for precautionary reasons, but after the contest, manager Ron Gardenhire said the team thinks it might be an inner-ear infection that was causing Morneau's dizziness.

"He was feeling pretty bad out there," Gardenhire said. "We got him out of there. He's day-to-day. See how he's feeling in the next day or so."

To replace Morneau, Brendan Harris shifted from shortstop to first base. Nick Punto moved from second base to shortstop and Alexi Casilla entered the contest to play second base.

Morneau went 0-for-2 with a strikeout before leaving.
