After battling tightness in his left hamstring since leaving Tuesday's game early, D-backs outfielder Justin Upton was back in the lineup Saturday against the Padres, batting fifth.
"After yesterday we didn't know what to expect but he went out and ran after the game and felt good," D-backs manager Kirk Gibson said. "He feels good today too, so he should be recharged and ready to go."
Saturday was also Upton's 25th birthday. The outfielder is in his fifth Major League season.
"He's still a youngster," Gibson said. "He's still pretty young, but he was really, really young when he came up."
D-backs pitcher Josh Collmenter tossed three scoreless innings with four strikeouts in a rehab appearance in the Arizona League on Friday.
The right-hander has been on the 15-day disabled list since Aug. 10 with ulcers.
"He threw great, lots of strikes, he feels good today," Gibson said. "He's got one more. Probably Tuesday. We'll see how he comes out of the next one."
