DETROIT -- The Rockies scratched left fielder Carlos Gonzalez from the lineup before Sunday afternoon's 5-0 loss to the Tigers because of a strained left knee.
An MRI did not reveal structural damage, and Gonzalez is considered day to day heading into a three-game series in Philadelphia starting Tuesday. Depending on how Gonzalez's knee responds to treatment, the Rockies -- reeling at 25-40, with losses in 10 of their last 11 games -- could be continuing a nine-game, 10-day road trip without their two main lineup forces.
Currently on the disabled list is shortstop Troy Tulowitzki, who will have his troublesome upper left leg checked by a sports hernia specialist in Philadelphia on Monday.
Gonzalez (.335, 17 HRs, 51 RBIs) described his problem as soreness at the back of the inside portion of his right knee. It was originally in the Comerica Park press box as right hamstring soreness. Gonzalez said he "tweaked" the knee in the eighth inning of Saturday's 4-1 loss to the Tigers and felt the pain worsen in the ninth, when he doubled and went to third on a wild throw to second base.
"I wasn't doing good after the game and last night," Gonzalez said after Sunday's game. "This morning I woke up a little better and tried to play through it. But I ran a couple of sprints before the game during stretching and I wasn't feeling right. It's prevention.
"Hopefully, I can get better and play on Tuesday."
It wasn't the news Rockies manager Jim Tracy needed Sunday afternoon just before turning in the lineup to the umpires.
"That's a punch in the news before you even get a chance to walk the cards out there," Tracy said.
Gonzalez has a seven-game hitting streak, during which he is hitting .438.
Additionally, Gonzalez and Tulowitzki are the only Rockies making impacts in voting for the National League squad for next month's All-Star Game in Kansas City. Tulowitzki went to the DL shortly before the last voting update, which had him with a narrow first-place lead over the Cardinals' Rafael Furcal. Gonzalez had risen from 13th place to 10th. The outfielders with the top three votes are starters.
Gonzalez's team has deeper concerns than his candidacy for the Midsummer Classic. After Tuesday's day off, the Rockies will play 20 straight days before the All-Star break.
"I don't want to be out of this lineup right now," Gonzalez said. "It would be even worse for the team. Having Tulo out, I just want to keep myself in there and wait for my shortstop to come back and play, and make this team better. We still have a lot of games to play."
