Marlins outfielder Mike Stanton exited Sunday's exhibition game in the second inning with a right quad strain. "I think the next couple of days will [give us] a better feel on a time frame," Stanton said when asked how long he might be out. "We really won't know for at least 24 or 48 hours." Stanton noted that he never experienced a quad injury before. "This is new territory for me," he said.

Phillies second baseman Chase Utley has patella tendinitis in his right knee and missed his second straight game Sunday. Utley underwent an MRI on Saturday. "It's been bothering him enough and bothering me enough, frankly, to go ahead and precautionary do that," general manager Ruben Amaro Jr. said of the MRI. "Rather than really pushing him early, we're going to kind of take it easy on him so there are residual effects throughout the year." His knee becomes painful in explosive baseball movements, such as running and fielding. "It's a little tendinitis in the knee," Utley said. "I've had it in the past. It comes and goes. It's not going [away] as fast as I wish it would, but I think at this point it's better to be safe than sorry. I'd rather miss a few games here than in the season." The Phillies don't have a timetable for Utley's first spring appearance.

Jason Bay appeared in left field for the Mets on Saturday, more than 200 days since he last played in a game. A concussion ended his 2010 season early. "As I got out there and kind of looked around, I was kind of thinking back like, 'Man, it's been a while,' " Bay said. Bay suggested, he had been symptom-free for so long, the significance of getting in the exhibition game was mostly an afterthought. "I've felt good for a while," said Bay, who played four innings in the field, along with the other Mets starters. "What was pleasantly surprising was it didn't feel like I was trying to overcome anything. I just kind of felt like I was going out there and getting ready. And I guess that's a good thing."

Red Sox second baseman Dustin Pedroia tested his foot in the team's 6-0 win over Boston College on Saturday. Pedroia was limited to just 73 games last season because of a fractured left foot. He walked a scored on a homer by Kevin Youkilis. "I wasn't out there very long but I felt good," Pedroia said. "My foot felt good. My timing's all jacked up but that takes some time. But, physically, I felt great." He had no defensive plays at second.

Orioles second baseman Brian Roberts missed a second straight day of spring training workouts because of a stiff neck. Roberts woke up Wednesday morning with neck stiffness, but X-rays came back negative. The injury forced him to forgo practice Wednesday, and he also skipped Thursday's session.

Rangers third baseman Adrian Beltre has a Grade I right calf muscle strain and will not take part in spring training games for 10 to 14 days. Texas doesn't believe the injury will hinder Beltre's ability to be ready for Opening Day. "Nobody wants to be hurt," Beltre said. "The positive side would be that it's better to happen now than during the season. I have time to get healthy."

Rangers pitcher Omar Beltre has had surgery after being diagnosed with a genetic narrowing of the spine. Texas assistant general manager Thad Levine said Thursday that there were no surprises and that the surgery a day earlier "went as well as could be expected." He is at least six weeks away from any baseball activities.

Rockies starter Aaron Cook, who has missed three days of pitching, will miss his first scheduled start of the spring because of continued setbacks from tightness in his shoulder and a bout with a stomach ailment. Colorado manager Jim Tracy said Thursday that Cook remains on a training program and that he will have to throw a bullpen session and likely throw live batting practice before he is cleared to pitch in an exhibition game. "He is getting stretched out to long distance and will eventually work his way back to the mound," Tracy said. "He had a couple of things he was battling early on and now he's progressing."

The Dodgers are hopeful that after Vicente Padilla underwent surgery to free a nerve that was trapped by a muscle in his right forearm that he could begin playing catch before the end of spring training. Los Angeles will still be without Padilla to begin the season. The surgery was performed by team physician Dr. Neal ElAttrache and Dr. Steve Shin, who conveyed the results to Dodgers trainer Stan Conte at Camelback Ranch. "Stan said it went well," Dodgers manager Don Mattingly said. "[Padilla] is supposed to be back in Arizona sometime [on Friday], and he'll start the rehab process. What I got was that his best outlook is three or four weeks, then he'll start tossing."

Rich Harden is pain-free and ready to resume his spring training regimen as soon as the Athletics give him clearance. Oakland was shut down last week and was expected to miss two weeks of workouts after experiencing stiffness in the lat muscle below his pitching arm when he tried to throw Feb. 15. Harden received a $1.5 million, one-year contract in December to rejoin the A's.
