LOS ANGELES - The Minnesota Twins tweeted late Friday afternoon that Rod Carew underwent a successful heart and kidney surgery. The Twins Hall of Famer is expected to make a full recovery.

The American Heart Association states on its website that Carew's transplant surgery began around 2 a.m. Central Time on Friday and is expected to take up to 18 hours.

Carew, 71, has been on the transplant waiting list for about a month but was moved up to the top of the list a week ago. On Wednesday, he and his family were informed that a donor was found.

Last September, Carew suffered a heart attack known as the "widowmaker," due to its low survival rate. While undergoing a procedure to open his clogged arteries, he went into cardiac arrest.

His family issued a statement asking all to keep "Rod in your prayers."

Friday's surgery removed the device that's been keeping Carew alive since that heart attack and cardiac arrest incident, then transplant the new heart and new kidney, which will help improve his chances of a stronger recovery.

The Twins released this statement late Friday afternoon:

“The entire Minnesota Twins family is happy to report that Rod Carew had a successful heart and kidney transplant surgery today at Cedar-Sinai Medical Center in Los Angeles, and is expected to make a full recovery. After a 13-hour procedure that started shortly after midnight Pacific time, Rod is resting in recovery. We ask that all of Twins Territory and the entire baseball community keep Rod, his wife Rhonda, and the entire Carew family in your thoughts and prayers as Rod recovers.”
