Federowicz could miss six to eight weeks, but that's to be determined when the extent of the damage is measured during the arthroscopic procedure. Black said Hoffman should be back and coaching much sooner. He took part in Wednesday's workout and then was slated to fly back to San Diego later in the afternoon. In the meantime, Jose Valentin will fill in for Hoffman in the third-base box.
"Hoffy's had some cartilage damage in his knee that he's been fighting, so he's going to go in also with Federowicz," Black said. "It's been off and on, and this spring, it just started acting up a little more. The doctors felt that now is the time to do it."
Hoffman has been the Padres' third-base coach for 10 seasons. He's the older brother of Padres great closer Trevor Hoffman, a Hall of Fame candidate for the first time later this year with a National League-record 601 saves. The younger Hoffman now has the title of Padres senior advisor, baseball operations. In reality, he's the organizational pitching coach, acting as a liaison between all levels of the Minor Leagues and the big league team.
