Percival and Maddon will now be reunited in Tampa Bay next season. Percival has signed to a two-year, $8 million contract with the Rays.
The deal also includes incentives for Percival that are based on appearances and games finished. The incentives could earn Percival another $4 million.
Percival has a long history as a closer, with 324 career saves, but he probably will fill a variety of roles for Tampa Bay, which has retained closer Al Reyes. The Rays also will probably value Percival for his old-school approach, something that could be a help with such a young team as Tampa Bay.
Percival came up with the Angels and pitched there from 1995-2004, being selected to four All-Star Games.
