Mariano Rivera told ESPN's Buster Olney that there's "a good chance" he would have retired had he been able to return last season to pitch in the playoffs.

It's an indication that 2013 will likely be his last season, though most were already assuming that it probably was. Mo will make an official announcement before the end of spring training about whether the upcoming campaign will be his final one.

Mariano Rivera (knee) threw a successful a 30-pitch bullpen session Saturday.

Rivera completed the session while wearing a protective brace on his surgically-repaired right knee, but didn't report any setbacks. The Yankees figure to limit his innings as a precautionary measure in spring training, so Rivera likely won't make a Grapefruit League appearance until later in March. The all-time saves leader remains on track to be ready for Opening Day.

Mariano Rivera said Wednesday that he will make an announcement before the end of spring training about whether 2013 will be his final season.

Rivera has already made up his mind on his future, but he isn't ready to make an announcement right now. The 43-year-old right-hander hasn't had any setbacks following right knee surgery and threw his first official bullpen session of the spring on Wednesday. He will wear a knee brace this season, but doesn't expect it to hinder him in any way. We wouldn't bet against him regaining his status as a top option at closer.

Mariano Rivera (knee) threw around 25 pitches in a bullpen session Wednesday.

Rivera was the center of attention Wednesday morning at Yankees' camp, as nearly 40 reporters watched him throw off the mound. The all-time saves leader didn't show any discomfort and remains on track for spring training and Opening Day.

Mariano Rivera (knee) is scheduled to throw a light bullpen session Wednesday.

It will be the first official bullpen session of the spring for Rivera, who is coming back from surgery to repair a torn ACL in his right knee. The 43-year-old said last month that he was at about 95 percent, so barring any unforeseen setbacks, he should be fine for spring training and Opening Day. He should be plenty valuable in fantasy leagues despite the absence.

According to MLB.com's Bryan Hoch, Mariano Rivera plans to begin his offseason throwing program next week.

Rivera is eight months removed from ACL surgery, and says his knee feels about "95 percent." He hasn't reported any setbacks in his rehab and remains on track to be cleared for spring training in February. All signs continue to points towards Rivera being ready for Opening Day.

Yankees re-signed RHP Mariano Rivera to a one-year, $10 million contract.

He'll have a chance to earn more through incentives. It was reported Thursday that the Yanks were on the verge of wrapping the deal with Rivera up, and now it's official. The future Hall of Famer takes a paycut from his $15 million salary from 2012, though perhaps the incentives would push the earnings up to around that mark. The 42-year-old is coming off surgery to repair a torn right ACL but is expected to be ready for spring training.

Jon Heyman of CBSSports.com reports that the Yankees and Mariano Rivera have agreed to a one-year, $10 million contract.

Heyman says the deal will also include incentives that could push the total higher. Once Rivera informed the Yankees earlier this month that he planned to return for 2013, there was little reason to believe hammering out a deal would take much effort. Mo takes a paycut from his $15 million salary from 2012, though perhaps the incentives would push the earnings up to around that mark. The 42-year-old is coming off surgery to repair a torn right ACL but is expected to be ready for spring training.

Jon Paul Morosi of FOXSports.com reports that the Yankees and Mariano Rivera are on the verge of agreeing on a one-year, $10 million contract.

Per Jayson Stark of ESPN, the deal could become official on Friday. Rivera earned $15 million this past season, so he's getting a pretty sizable pay cut in base salary, but there are likely some incentives involved. The 42-year-old right-hander is coming off surgery to repair a torn right ACL, but he's expected to be ready to go for spring training.

The Yankees are planning to complete a pact with Mariano Rivera on Friday, reports ESPN's Jayson Stark.

"The two sides have agreed on the parameters of a one-year deal," writes Stark, and are finishing up the details of that contract Thursday. Rivera is coming off surgery for a torn right ACL but is fully expected to be ready for the start of spring training next February. The 43-year-old right-hander was limited to just 8 1/3 innings in 2012.

Ken Rosenthal of FOXSports.com reports that the Yankees are optimistic about completing a deal with Mariano Rivera this week.

Mariano Rivera threw off a mound Friday for the first time since undergoing surgery to repair a torn ACL in his right knee in May.

He threw 25 pitches in all. Oddly enough, Rivera made the throws during a commercial shoot on a snow-covered field at Hackley School in Tarrytown, New York. The 42-year-old right-hander recently said that he plans to pitch in 2013, so it's just a matter of him working out a new contract. Jon Heyman of CBSSports.com reported earlier this week that the Yankees will likely ask him to take a paycut from the $15 million he made in 2012.

According to Jon Heyman of CBSSports.com, the Yankees are expected to ask Mariano Rivera to take a "significant paycut" as part of a new contract.

Rivera made $15 million this season, but estimates for a new offer are closer to a $10 million base salary which would likely include incentives to boost his pay. The thought is that the Yankees have leverage, as the 42-year-old right-hander is coming off knee surgery and won't pitch anywhere else.

The New York Post reports Mariano Rivera (knee) will return for the 2013 season.

Rivera, out since early May with a torn ACL, was believed to be having second thoughts about possibly retiring. General manager Brian Cashman has confirmed that won't happen and Rivera will be back for a final season. After making $15 million in 2012, the Yankees are expected to re-sign him to a one-year contract this winter.

Andrew Marchand of ESPN New York writes that while it is still "probable" that Mariano Rivera (knee) will return next season, he is having second thoughts about possibly retiring.

Rivera vowed to return after tearing the ACL in his right knee back in May and has worked very hard in his rehab, but Yankees manager Joe Girardi hedged when asked about the situation earlier this week. Rivera is a free agent this winter, so Girardi likely didn't want to commit to a player who wasn't signed yet, but the all-time saves leader turns 43 years old next month and has previously said that he wants to go out as an elite player. If he doesn't feel he can do that, it's possible he will call it a career. However, we have a feeling he hasn't thrown his last cutter.

Mariano Rivera (knee) threw long toss Monday.

Nice to hear, as Rivera is little over two months removed from surgery to repair a torn ACL in his right knee. Still, the Yankees aren't expecting him back in 2012.

Yankees general manager Brian Cashman reiterated Tuesday that he doesn't think Mariano Rivera (knee) will pitch again this season.

Dr. Keith Pyne's comments to the New York Post have created quite a bit of chatter Tuesday, but this is pretty much what we expected Cashman to say. Rivera remains a tremendous long shot to pitch this season, so the Yankees are expecting nothing.

Mariano Rivera underwent ACL surgery Tuesday.

The procedure went as planned and was deemed an initial success. Rivera is done for the rest of the season.

Mariano Rivera's ACL surgery has been scheduled for June 12.

Rivera's blood clot issue has been resolved, so he's now ready to go under the knife. The future Hall of Famer expects to be completely healed by spring training next year.

Yankees transferred RHP Mariano Rivera from the 15-day disabled list to the 60-day disabled list.

It clears a spot on the 40-man roster for Andy Pettitte. Rivera is out for the season with a torn meniscus and ACL in his right knee.
