According to Nick Cafardo and Peter Abraham of the Boston Globe, the Red Sox have signed right-hander Alfredo Aceves to a major league contract.

The Boston Globe's Nick Cafardo reports that the Red Sox are interested in free agent Alfredo Aceves.

Aceves made only 10 appearances this past season due to a back problem and then complicated matters when he broke his clavicle in a bicycle accident over the winter, which led to him getting non-tendered. He's expected to be ready to pitch at some point during spring training, though, and would make for a nice buy-low candidate. The righty boasts a 3.21 ERA, 1.06 WHIP and 87/30 K/BB ratio over 126 career innings.

Contrary to an earlier report, free agent Alfredo Aceves (clavicle) has not experienced a setback and is expected to be ready to pitch by March.

Wallace Matthews of ESPN New York said in a chat with readers Wednesday that Aceves was going to miss most, if not all, of the 2011 season. But that information was not correct in the slightest. Aceves should be recovered from his back injury and broken clavicle (collarbone) shortly after the start of spring training. He remains an unsigned free agent to this point.

Alfredo Aceves (back) is not expected to pitch in 2011.

And now we know why the Yankees decided to non-tender the righty. Aceves was plagued by a back injury throughout the 2011 season and made it worse when he got into a bicycle accident this winter. He's going to sit out for at least the first several months of this upcoming season, and probably longer.

Joel Sherman of the New York Post reports that the Rockies have expressed interest in free agent right-hander Alfredo Aceves.

Aceves was non-tendered by the Yankees earlier this month after fracturing his left clavicle in a bicycle accident. He probably won't be fully healthy by Opening Day, but the 28-year-old did rattled off a 3.00 ERA and 1.17 WHIP over 12 innings of work this past season in New York.

Yankees non-tendered RHP Alfredo Aceves.

Things might have been different had Aceves not fractured his left clavicle in a bicycle accident Tuesday. He posted a solid 3.00 ERA and 1.17 WHIP over 12 innings of relief this year for the Yankees and should draw interest on the open market. The righty earned $436,650 in 2010.

Alfredo Aceves suffered a fractured left clavicle in a bicycle accident Tuesday and underwent surgery immediately.

The Yankees have been told that he will need six weeks of rest and three months of rehab. In other words, he probably won't be back to full health by the time spring training opens. Aceves posted a solid 3.00 ERA and 1.17 WHIP over 12 innings of relief this past season for New York.

Yankees manager Joe Girardi doesn't expect Alfredo Aceves (back) to return this season.

Aceves has been on the disabled list since the early part of May due to a bulging disk in his lower back. He was making solid progress recently until being scratched from a rehab start with Triple-A Scranton/Wilkes-Barre last week.

Alfred Aceves was scratched from a rehab appearance Thursday at Triple-A Scranton/Wilkes-Barre after re-aggravating a back injury.

Aceves is headed to New York to have his back examined. He has been sidelined since early May and might be in danger of missing the rest of the regular season if new tests reveal anything mildly serious. The righty had a 1.17 WHIP and 3.00 ERA in 12 innings of relief before going down.

Alfredo Aceves (back) struggled Tuesday in a rehab appearance for Double-A Trenton, giving up six hits and three runs over 1 1/3 innings.

Yankees manager Joe Girardi said before Aceves pitched Tuesday that the righty needed to be a little sharper before getting recalled. Needless to say, he probably hasn't changed his mind. Aceves is likely to be back in September and used as a long reliever.

Alfredo Aceves (back) is expected to make another minor league rehab appearance on Tuesday.

It's not known where he'll pitch, but it's reasonable to speculate that it will be with Double-A Trenton, where he appeared over the weekend. Aceves allowed one run over 2 1/3 innings with the Thunder on Saturday night. If all goes well Tuesday, he could finally return from the disabled list. The 27-year-old right-hander has been on the shelf since early May due to a lower back injury.

Alfredo Aceves (back) allowed one run in 2 1/3 innings during a minor league rehab appearance with Double-A Trenton on Tuesday.

Aceves allowed one hit and struck out four, throwing 24 out of 35 pitches for strikes. Yankees general manager Brian Cashman said that he will need at least one more rehab appearance before being activated from the disabled list. Aceves has been sidelined since the early part of May due to a lower back injury.

Alfredo Aceves (back) threw two scoreless innings in a rehab appearances for Double-A Trenton Friday.

It's the second appearances he's made. "I didn't feel anything in my back," said Aceves. "That's the important thing." The right-hander expects to make 1-2 more appearances before returning to the Yankees, which means he could be back in about a week. He's been on the DL since mid-May.

Alfredo Aceves (back) will make his first rehab appearance with Triple-A Scranton/Wilkes-Barre on Tuesday.

Aceves is on the 60-day DL, but he's eligible to return next week. How he performs will Scranton will determine whether he's activated prior to Sept. 1.

Alfredo Aceves (back) is making progress in his bullpen sessions.

"I am encouraged, but we are not out of the woods yet," Yankees manager Joe Girardi said. "But if he could pitch like he did last year and earlier this year it would be helpful." Aceves hasn't pitched since May 8 due to a bulging disk in his lower back. He's still a ways away from a return.

Alfredo Aceves (back) is headed to New York for further evaluation after suffering another setback during a bullpen session Monday.

Not a good sign. The Yankees hoped to get Aceves back shortly after the All-Star break, but now his status is TBA. With this sort of uncertainty and the struggles of Joba Chamberlain and Chan Ho Park, look for the Bombers to be in the market for a right-handed reliever around the trade deadline.

Alfredo Aceves (back) is scheduled to throw another bullpen session on Friday.

Aceves also threw bullpen sessions on Monday and Wednesday. There's no current timetable for his return.

Alfredo Aceves (back) is expected to throw off a mound on Monday in Tampa.

As far as progress, Yankees manager Joe Girardi believes Aceves is slightly behind Sergio Mitre at the moment. Aceves hasn't pitched since May 8 due to a bulging disk in his lower back. Like Mitre, he'll need a rehab assignment before being activated from the disabled list.

Alfredo Aceves (back) played long toss on Tuesday.

Aceves is slowly working his way back from a back injury. He threw a bullpen session off a half-mound over the weekend, but has not yet done the real thing. Thus, he's still at least a week from returning.

Alfredo Aceves (back) threw off a half-mound on Saturday as part of his return from his lingering back injury.

It's not quite a full bullpen session, but it's all heading in the right direction for Aceves, and not a moment too soon, considering the state of the Yankees' bullpen. He's still a ways from returning, but he'll surely be welcomed back with open arms when he's ready to go.
