With Justin Morneau out of the lineup for the second straight day battling sickness, Joe Mauer is set to play first base Sunday afternoon at Target Field in the rubber match of the Twins' three-game series against the Seattle Mariners.

Twins manager Ron Gardenhire said Morneau left him a text message saying that if Morneau played at all, it would have to be as a designated hitter.

After reading that, Gardenhire opted to give the Twins first baseman the day off.

"He's here and we'll see about availability going on," Gardenhire said.

Morneau missed Saturday's game with flulike symptoms as well.
