MILWAUKEE -- Cubs third baseman Aramis Ramirez has a strained left knee and will undergo an MRI Thursday in Chicago. His status is day-to-day.
Ramirez originally injured his knee during the Cubs' series in Philadelphia May 11-13. On Wednesday, he was trying to beat the throw from Milwaukee shortstop J.J. Hardy in the second, and was safe on a fielding error by the infielder. Ramirez appeared to be hobbling after he reached first base. He stayed in the game and was lifted defensively in the Brewers second inning.
"It's been sore for two or three weeks," Ramirez said. "I was able to play. When I stepped on first, I stepped kind of hard. It's pretty sore, so I'm going to go to Chicago and see what happens."
Ramirez said he wasn't too worried about the injury.
"Nobody's 100 percent," he said. "If you're an everyday player, you're not 100 percent. You have to be able to play through injuries. I'll get back in the lineup as soon as I can."
Ramirez was batting .299 with 13 home runs and 39 RBIs. He also reached in the first inning on a fielding error by Hardy. The Cubs third baseman is second in RBIs for National League third basemen, two behind Florida's Miguel Cabrera.
