Rollins sits as precaution with minor groin issue

PHILADELPHIA -- Phillies shortstop Jimmy Rollins was held out of the starting lineup for Monday's series opener against the Blue Jays as a precaution after tweaking his right groin in Sunday's win over the Nationals.

Rollins said he could have started against Toronto, but wanted to make sure he didn't do something to worsen a minor injury. Phillies manager Ryne Sandberg said Rollins would be available off the bench as a pinch-hitter. Freddy Galvis got the start at shortstop.

Rollins said he "felt a little something" in the groin during the top of the fifth inning on Sunday, when he fielded three straight ground balls. But he played all nine innings.

"It wasn't anything that would take me out the game," Rollins said Monday. "I'm just taking a day off."

Sandberg said he was not worried about Rollins' health.

"Just felt a very little, small thing that he played through," Sandberg said. "He reported fine. It'd be smart to get him off his feet today. Also allows Freddy to get in there and play a game at short."

Ruiz's versatility gives Ryno lineup options

PHILADELPHIA -- Carlos Ruiz has been one of the Phillies' most productive hitters this season, allowing manager Ryne Sandberg to slot the catcher virtually anywhere in the lineup.

Ruiz is second on the team to Chase Utley with a .286 batting average, .400 on-base percentage and .852 OPS through 24 games, entering Monday's action. The veteran has appeared everywhere in the lineup except leadoff, eighth and ninth.

"He's a guy that I can be flexible with in a lot of different ways," Sandberg said before Monday's game against the Blue Jays.

Ruiz batted sixth on Monday, providing protection behind Ryan Howard. With Jimmy Rollins out of the lineup, Sandberg decided to slot Freddy Galvis (.088 on-base percentage) in the No. 2 hole instead of Ruiz.

"[Ruiz is] also a good bat against a left-handed pitcher behind Howard, and that puts him in an RBI situation, so then his knack of getting on base is also hitting the ball," Sandberg said. "Preferably, if we can have some men on base, he's a good bat right there behind Howard in an RBI situation."

Galvis is in a 1-for-31 skid to start the season, entering Monday's game. But Sandberg said he put the infielder near the top of the lineup for some "situational hitting."

"Maybe move a runner, maybe lay down a bunt, hit and run," the manager said. "[Galvis is] also a base-runner. We've been good at having guys get on base at the top of the order. That's been a real good thing for us the last couple weeks, so we'll look to him to do the job in that spot."

Phils prospect Martin begins rehab assignment

PHILADELPHIA -- Phillies right-hander Ethan Martin began a Minor League rehab assignment on Sunday, pitching a scoreless inning with Class A Advanced Clearwater.

Martin, ranked No. 8 on MLB.com's Top 20 Phillies Prospects list, began the season on the 15-day disabled list after straining his right shoulder during Spring Training. He started eight games for the Phillies last year, but the club decided to send him to the bullpen after his injury. In addition to building arm strength during his rehab assignment, Martin still needs some seasoning as a reliever.

"Yeah, just monitor him, see what he looks like," Phillies manager Ryne Sandberg said Monday. "There's some grooming there, but it'll also allow him to build his arm up at a reasonable pace, reasonable time frame, but also keep tabs on him."

Worth noting

Cole Hamels is "all set to go" for Tuesday's start against the Blue Jays, Sandberg said. The left-hander had his scheduled start Sunday pushed back because of the flu.
