CHICAGO -- Outfielder Jacque Jones was expected to miss the Chicago Cubs' weekend series in Pittsburgh to give his sore right hamstring time to heal.
Jones had to come out of Tuesday's game because of the injury and an MRI revealed a mild strain.
"I've learned from hamstrings that when a guy says he feels good, you give him a couple extra days," Cubs manager Dusty Baker said Thursday. "You invariably end up topping a ball and have to beat it out. It happens every time. You may not have an infield-hit situation for a month and as soon as you hurt your legs, it happens. I've learned to give them a couple extra days."
Jones did take batting practice Thursday, but agreed he'll likely miss playing the Pirates.
"I don't want to ruin myself for two-to-three weeks," he said.
After Pittsburgh, the Cubs travel to Los Angeles for a three-game series where it should be warmer -- but possibly wet because of all the rain.
Meanwhile, Aramis Ramirez, sidelined with a strained buttocks muscle, was making progress. The injury was most likely caused by overswinging.
"That's probably it," Ramirez said. "I always swing hard."
This setback may actually help the third baseman.
"I think I was doing it a little bit, I was overswinging," Ramirez said. "I was swinging too hard and trying too hard. I have to relax. This could actually help me. I'll sit down a couple games and relax and come back ready to go."
Baker said he expects Ramirez to be able to play in Pittsburgh.
"At this juncture in the season, we want him to feel great," Baker said. "We want him better, but we prefer great."
