Aaron Boone is likely to retire, according to Bob Nightengale of USA Today (via Twitter). Boone, 36, worked hard to rehab from March open heart surgery and picked up 14 plate appearances at the end of the season.
Boone would finish with a career line of .263/.326/.425 in 4,329 plate appearances, mostly as a third baseman. He played for the Reds, Yankees, Indians, Marlins, Nationals, and Astros. He's best known for his home run off Tim Wakefield in the 2003 ALCS, which gave the Yanks the AL pennant over the Red Sox. Several months later, Boone's ACL tear prompted the Yankees to acquire Alex Rodriguez.
