The San Diego Padres plan to retire Trevor Hoffman's No. 51 in a ceremony on Aug. 21 after a game against the Florida Marlins.

Hoffman, baseball's all-time leader with 601 saves, retired in January after playing 18 big league seasons. He's a special assistant in the Padres' front office.

Hoffman was picked by the Marlins in the 1992 expansion draft and made his big league debut in 1993. After getting two saves with the Marlins, he was acquired by the Padres in a five-player trade on June 24, 1993, as part of San Diego's "fire sale." That trade sent Gary Sheffield to the Marlins.

Hoffman had 552 saves with the Padres before playing his final two seasons with Milwaukee, where he had 47 saves.
