On May 3, all-time saves leader and Yankee legend Mariano Rivera injured his ACL while shagging balls in the outfield before their evening game against the Kansas City Royals. This injury could potentially be devastating for the Yankees, as they currently sit in fourth place in the tough AL East Division, only ahead of rival Boston.
Rivera has been clutch as the Yankees closer, as he's the all-time leader in saves and has the lowest ERA and WHIP of any pitcher of the live-ball era. He might be the most missed if the Yankees make the playoffs, as he also holds the lowest playoff ERA and has the most saves (42) of any reliever.
While it's still early in the 2012 season, the always busy Yankees should already start considering trying to replace Rivera on their staff, as he's expected to miss the entire season with the potentially career-ending injury. Here's a list of 10 relievers who could try to fill the huge shoes of the future Hall of Famer.
