"We just wanted to keep him in the organization," Rays manager Joe Maddon said. "He's a bright young man. We're not quite sure how this is going to work yet."
Anderson, 35, came to camp this spring after signing a Minor League contract with an invite to Major League camp, but then suffered a career-ending tear in the ulnar collateral ligament and the flexor mass muscle in his left elbow.
Maddon said Anderson will help pitching coach Jim Hickey in addition to reviewing scouting reports, scout during the games and help during workouts. He will not travel with the team, but he will be in uniform prior to home games.
"It's kind of an interesting concept," said Maddon. "And again, he's just the right kind of guy to do it with. We wouldn't just do this with just anybody. And we feel as though he has the intelligence and experience to really create this position for."
Anderson said he was surprised by the offer.
"I haven't been around that long," Anderson said. "When I got hurt, I figured I'd go home. ... It was an honor to even be considered. ... I think this is going to be an evolving role."
Anderson was drafted third overall by the Angels in the 1993 First-Year Player Draft and made his Major League debut later that year. Arizona selected him from Cleveland with its first pick in the November 1997 Expansion Draft, immediately after the Rays drafted Tony Saunders first overall.
He owns a career record of 82-83 with a 4.74 ERA, having pitched for the Angels (1993-95), Indians (1996-97, 2003), Diamondbacks (1998-2002), and Royals (2003-05). He won a championship with Arizona in 2001 and also reached the postseason in 1997 and 1999, compiling a 2.43 ERA, 2-1 record and one save in 11 playoff appearances.
