Rockies pitcher Jorge De La Rosa surrendered only one hit his last time out, but a nagging back injury may limit him in his start against the Giants at Coors Field on Thursday.
"I didn't do running," De La Rosa said. "I did elliptical and a lot of stretching. That's all I can do. I feel better but I still can't run too much."
De La Rosa (5-3) aggravated a back injury that flared up after his win against the Rangers during his seven-inning, one-hit performance against the Padres on May 16. He also pitched with a bruised left middle finger, but the injuries didn't stop him from picking up five strikeouts in his last victory.
"I just attack the hitter," De La Rosa said. "That's all that's on my mind. I know I hurt sometimes but I try to keep that out of my mind."
However, De La Rosa said the injury doesn't affect him when he pitches, only when he runs the bases.
If his back doesn't act up, De La Rosa could be a valuable asset against the Giants on Thursday. For his career, the 33-year-old left-hander is 9-5 with a 4.15 ERA against San Francisco. The Rockies are 8-1 in De La Rosa's starts against the Giants at Coors Field.
His last start against the Giants was forgettable, though. Pitcher Madison Bumgarner hit a grand slam off De La Rosa, and the Rockies lefty gave up six runs on four hits and two walks in 4 1/3 innings.
Giants: Pence stands alone
Right fielder Hunter Pence became MLB's active leader in consecutive games played with 353, including 218 starts in a row.
Rangers first baseman Prince Fielder was the previous leader, but a herniated disk in his neck forced him out of the lineup last Saturday, ending his streak at 547 games in a row.
Pence is also the only Giant to have started every game this season while playing every inning.
Rockies: No hard feelings
Beanballs flew in the first two games of the Giants-Rockies series.
In the first game of the series Tuesday night, Bumgarner hit Rockies star shortstop Troy Tulowitzki in the leg with a pitch. In the seventh inning, Rockies reliever Rex Brothers hit Bumgarner.
"I know Bumgarner wasn't hit intentionally, and I don't think Bumgarner was trying to hit Tulo," Rockies manager Walt Weiss said before Wednesday's game. "I think Bumgarner was throwing a cutter and he wanted to make sure he didn't leave it out over the plate and get that cutter in on Tulo and hit him on the lower leg. Certainly, when Rex hit Bumgarner, we didn't want to put the winning run on at that point in the game with two outs."
But in the second inning of Game 2 of the series, Giants starter Matt Cain hit Rockies first baseman Justin Morneau. Home-plate umpire Adam Hamari quickly issued warnings to both sides and there were no further incidents.
Giants: SF facing tough schedule
The Giants have endured difficult stretches of games so far this season, and they are in the midst of another.
San Francisco is currently in a stretch of 14 straight games against teams with a .500 record or better. If the Twins, who entered Wednesday with a 22-21 mark, maintain their above-.500 record, that streak will move to 17 games when they come to AT&T Park for this weekend's three-game series.
After Minnesota comes a three-game series with the Cubs, who have the Major Leagues' worst record (16-28) after Wednesday's 13-inning, 4-2 loss to the Yankees.
But after they face the Cubs, the Giants travel to St. Louis and Cincinnati to face the Cardinals and Reds, who went a combined 10-3 against the Giants in 2013.
The schedule doesn't get any easier when the Giants return to AT&T Park. They'll face the Mets, Nationals and Rockies -- the latter two are both above .500. By the time they face the Rockies again, the Giants should have a clearer view of what needs they have to fill at the Trade Deadline.
• With Wednesday's 5-1 victory, the Giants held the opposition to one run or fewer for the 13th time this year, second in the NL behind the Reds.
