Ramirez, who is scuffling at .160, did not play Sunday in the Cubs' Interleague series finale against the Rangers, which they won, 5-4. He has a bruise and mild sprain of his left thumb. The problem is at the base of the thumb.
"We're going to give him a little time off," Cubs manager Lou Piniella said after Sunday's win. "He's struggled at home plate. We need to give him some time. Sometimes time heals wounds. You work and you work and sometimes it's better to get away from it totally and just relax."
However, Ramirez's thumb is not bad enough to prompt the Cubs to put him on the disabled list.
"According to what the trainer has told me numerous times, it's just a bone bruise," Piniella said.
Expect to see Jeff Baker and Mike Fontenot at third base.
"I would think a few days will do [Ramirez] good," Piniella said.
