RHP Jarred Cosart (hamstring) is scheduled to throw a bullpen session Saturday in San Francisco to evaluate the status of his injury. He is eligible to be reinstated from the 10-day disabled list, so a positive report could result in Cosart returning to the Padres bullpen as early as Sunday.

RHP Jarred Cosart (hamstring) ran at about 90 percent at the Padres' spring training facility in suburban Peoria, Ariz., on Tuesday, manager Andy Green reported. "He was moving well," Green said. "We are going to sit down the next day and try to map out his path." RHP Luis Perdomo replaced Cosart the last time through the rotation. Cosart, 0-1 with a 3.24 ERA in three starts covering 8 1/3 innings, was placed on the disabled list April 19.

RHP Jarred Cosart was placed on the 10-day disabled list due to the right hamstring strain he suffered Tuesday night while running out a bunt. "We're hoping it is nothing overly serious," manager Andy Green said. "But it was serious enough that he had to come out of the game yesterday in the middle of it. A hamstring is like a shoulder at times. You just have to wait until it feels good. If it feels good, we'll move to accelerate his path back as quickly as possible."

RHP Jarred Cosart left Tuesday's start with a strained right hamstring and is questionable for his next start scheduled for Sunday. Cosart, who pitched four scoreless innings in his first start of the season April 10 in Colorado, retired the first 10 Diamondbacks he faced Tuesday, but he felt the hamstring getting tighter as the fourth inning progressed and left with the game tied at 1-1 and the bases loaded. Two of those runners scored on an error, giving Cosart the loss. "It's pretty sore," Cosart said after the game of the injury.

RHP Jarred Cosart will make his second start on Tuesday when the Padres open a three-game home series with Arizona.

He had been in the Padres bullpen this season and allowed two runs on a hit and three walks in two-thirds of an inning in his only appearance.

RHP Jarred Cosart continues to make his transition from starter to reliever. "He still has to acclimate down there," manager Andy Green said. "Coming out from the 'pen is new for him, and it might take him a little time. But the arm is live and his stuff plays out of the 'pen."

Only 16 of his 33 pitches went for strikes, although his velocity was still around 95 toward the end of the inning.

RHP Jarred Cosart made his first career start against the Rockies and allowed five runs on five hits and four walks in 3 2/3 innings with four strikeouts. All the runs and three of the walks -- all consecutive -- came in the fourth. Cosart allowed a two-run homer to Mark Reynolds after a bloop double by David Dahl and then gave up a two-out single to No. 8 hitter Tony Wolters followed by three straight walks. Padres manager Andy Green said, "He was throwing the ball really well, got through the first three innings very nicely, but it's something that I've seen from a number of our pitchers, especially some of the starters that we tried to incorporate into the rotation. You look up and one bad break occurs, and it seems to derail guys. It seems to get them to the point where they start thinking about the bad break. You know, David Dahl hits a relatively cheap hit down the left field line, and then you hang one pitch and Mark Reynolds makes you pay for it. And then after that, it's like things go fast. That's the challenge for him, that's the challenge for a lot of our guys. When you get in that situation and things are going fast, it's not going the way you want it to for a batter or two, like how do you bring it back? How do you stop that five-run inning from happening?"
