Rivera has converted four straight save opportunities since blowing his first save of the season on May 28 against the crosstown Mets.

Mariano Rivera blew his first save of the season Tuesday, giving up two runs in a loss to the Mets.

Rivera threw out the first pitch before the game, but it was his last that ended it in ugly fashion for the visitors. Rivera didn't get a single out in the loss, as he gave up a leadoff double to Daniel Murphy before consecutive singles by David Wright and Lucas Duda ended his evening. The blown save was aided by a Brett Gardner fielding error, but the 43-year-old was just off his game this night. The Yankees aren't too concerned with the outing, and we're not, either.

Mariano Rivera worked a scoreless ninth inning Saturday against the Royals, preserving a one-run lead and notching his 14th save of the season in the process.

Rivera is once again tied with Jim Johnson for the American League lead with 14 saves. It's simply incredible what he's been able to accomplish this season at 43 years old and after missing nearly the entire 2012 campaign. Through his first 16 appearances, Mo owns a 1.76 ERA, 0.98 WHIP and 12/2 K/BB ratio. He has converted all 14 of his save opportunities.

Mariano Rivera got the final out for his 10th save of the year Tuesday against the Astros.

It was about as easy a save as a closer can get. Still, he was up to the task, striking out Jason Castro to end the game. Mo is now tied for the league lead in saves.

Mariano Rivera converted his third save of the season Tuesday, closing out the Diamondbacks.

It was the first appearance in which Rivera didn't allow a baserunner, a positive for the 43-year-old reliever. He also struck out one in the outing. He isn't an elite closer anymore, but he's plenty serviceable in all leagues.

Mariano Rivera gave up a run Thursday in his 2013 debut, but he did pick up a save after entering a 4-1 game against the Red Sox.

Rivera got Will Middlebrooks to ground out and then struck out Jackie Bradley Jr. on three pitches to end the game. Of course, no one ever gets hits off Rivera the first time they face him. Still, he did look rather human tonight while walking Dustin Pedroia and giving up a double to Jonny Gomes.

Mariano Rivera has been diagnosed with migraine headaches.

Mo has been having headaches for a couple weeks now, so the Yankees decided to get him checked out Friday. "When you have issues you want to make sure everything is OK,'' Rivera said of the CAT-scan and blood test. "They said it seems like migraine headaches.'' Rivera has pitched great this spring and it doesn't appear that the headaches will affect his availability for Opening Day. It's a situation to monitor.

It's the first time he's faced hitters since blowing out his knee last May. "Basically just wanted to see the hitters, that's it," Rivera said. "I don't do nothing different than the bullpen, but seeing the hitters, seeing how they swing at the ball. . The first BP that I threw in almost a year. I'm really happy with the results. It will get better. The longer I keep throwing, it will get better." Mo is expected to be ready to roll on Opening Day.
