The Diamondbacks fired manager Bob Brenly yesterday in the midst of their worst season since their expansion campaign of 1998.

Third base coach Al Pedrique was named manager for the remainder of the season.

Hall of Famer Robin Yount, the team's bench coach, resigned out of loyalty to Brenly, GM Joe Garagiola Jr. said. Pitching coach Chuck Kniffin also was fired.

Pedrique, who played parts of three seasons with the Mets, Pirates and Tigers, was a manager in the minors for eight seasons. He managed Arizona's Class AAA Tucson Sidewinders in 2002 and '03.

"I have mixed feelings," Pedrique said, "because definitely I wanted to manage in the major leagues. But it never crossed my mind that it would be like this."

Pedrique joins Ozzie Guillen of the White Sox as the only Venezuelans to manage in the majors.

* BOSTON MOVES: Red Sox 3B Bill Mueller, who had been on the disabled list since May 20, returned to the lineup last night, but the team placed top reliever Scott Williamson on the 15-day DL with a nerve impingement in his right forearm.

To make room for Mueller, IF Cesar Crespo was designated for assignment; RHP Anastacio Martinez was recalled from Class AAA Pawtucket to fill Williamson's roster spot.
