ST. PETERSBURG -- Don Zimmer, the Rays' senior baseball advisor, underwent more than six hours of surgery on Wednesday to repair a leaky valve in his heart. The Rays reported on Thursday that Zimmer is resting comfortably and is expected to remain in the hospital a few days while he recovers.
Zimmer, who is in his 66th season of professional baseball, has worn 14 Major League uniforms as a player, manager and coach, but he spent the most time in a Rays uniform (11 seasons).
The surgery took place on the same day the Rays wore No. 42 in honor of Jackie Robinson (a day late because of Tuesday's rainout in Baltimore). Zimmer was a teammate of Robinson's on the Brooklyn Dodgers from 1954-56.
