The New York Yankees and closer Mariano Rivera are close to an agreement, and should have one finished by Friday, according to ESPN NewYork. The site also reports that the one-year deal is expected to fall between $11 and $12 million plus incentives.

There is still concern over Rivera's health, as he missed nearly all of 2012 with a torn ACL suffered while shagging fly balls. At the time, some thought Rivera's career over.

Rivera has spent his entire professional baseball career in the Yankees organization. He first signed with the team in 1990, and debuted with the major league club in 1995. Since then, he has been the game's premier closer and a key member of five World Series Championship squads. He holds the MLB record for saves at 608, and didn't appear to be slowing down until his injury last April. In 2011, he tallied 44 saves with a 1.91 ERA.
