Roy Halladay battled back and shoulder issues last season, but the Phillies are optimistic about his health heading into the 2013 season.

"Doc's done very well. He's going to start throwing off the mound here very shortly," Ruben Amaro said.

"[Pitching coach Rich Dubee] has seen him throw a couple times, at least long toss. I guess he's working down there with Kyle Kendrick pretty extensively. He's doing well, but we don't know what kind of Doc we're going to get until Doc's down firing in Spring Training. But he's feeling pretty good so far."

Justin Morneau hit .267/.333/.440 with 19 home runs and 570 plate appearances in 2012, a season that would be considered a healthy one by his recent standards.

He suffered a career-threatening concussion in 2010.

For the first time in what seems like forever, Morneau is preparing for the 2013 season ahead of spring training at full strength.

"... Everything this winter has been totally different -- no restrictions with the concussion stuff," he told Phil Mackey of 1500 ESPN Radio. "I've been able to do everything I've wanted to do, and it's been a good feeling. I'm starting to get excited for the season, instead of feeling like I'm starting behind the 8-ball."

The Blue Jays have made several splashes this offseason, but the health of Jose Bautista has rarely been discussed.

Bautista has hit more home runs than any other Major League player since 2010.

He missed virtually the entire second half of 2012 after sustaining an injury to his left wrist just four days after the All-Star break. Eventually, he underwent surgery to repair a damaged tendon sheath in his left wrist.

The Blue Jays maintain that their right fielder will be ready for spring training, but there may be reason to believe it won't be quite the same guy taking the field in 2013.

"If you have surgery on your fingers or your hands, it is so easy to screw up the mechanism," says Edward McDevitt, an orthopedic surgeon and member of the American Orthopedic Society for Sports Medicine.

"And if you're a professional baseball player, where the ability to use your fingers and your hands is so critical to holding a bat ... it's not always easy to come back."

The Red Sox have received some calls about Jarrod Saltalamacchia, according to a report.

It would appear as though Boston hasn't received an offer that they like as they have yet to pull the trigger.

Saltalamacchia is coming off a year in which he hit .222 with 25 home runs and 59 RBIs in 121 games.

Scott Diamond has undergone surgery to remove a bone chip from his left elbow, but will be ready for Spring Training.

Diamond, 26, had the arthroscopic surgery done by Dr. David Altchek in New York on Tuesday.

"He'll be ready for Spring Training," Terry Ryan said. "But he will not participate in the World Baseball Classic."

Diamond was set to play for Team Canada after a breakout season in 2012.

The Red Sox reached a three-year, $39 million agreement with Mike Napoli 18 days ago, but the contract still isn't official.

Napoli has a problem with one of his hips, which led the Mariners to back off their pursuit in free agency, according to sources.

The issues may have also concerned the Rangers.

Mariano Rivera expects to be healthy enough to close for the Yankees by Opening Day 2013.

Rivera is recovering from surgery to repair a tear in his right anterior cruciate ligament suffered in a batting practice mishap on May 3 in Kansas City.

"Oh yeah, I don't see why not," he said of being ready for the April 1 opener. "We have at least three months, four months to that point. I'll be ready."

Rivera has signed a one-year, $10 million contract to continue his career.

The Mets continue to ask for a lot in return for R.A. Dickey should they trade him.

Dickey, who won the 2012 NL Cy Young, is under contract for $5 million for next season.

Alex Rodriguez will have surgery on his left hip in mid-January and is eager to return to the Yankees.

It's expected that Rodriguez, who will be making his sixth trip to the disabled list in six seasons, could be sidelined until the All-Star break.

"I'm not concerned," Rodriguez said. "I'm actually, in many ways, relieved that there's something tangible that we can go fix."

Grady Sizemore, who is a free agent, underwent microfracture surgery on his right knee in September, his agent has confirmed.

He may not be ready to play in a Major League game until midseason.

Sizemore previously had microfracture surgery on his left knee in 2010. He didn't play at all in 2012.
