Royals staff shaken up

? Tom Gamboa, the Kansas City Royals’ coach attacked near first base last month in Chicago, will be shifted to the bullpen.

The Royals also added former Chicago Cubs hitting coach Jeff Pentland to their 2003 coaching staff in changes announced Thursday by manager Tony Pena.

Pentland was hired to replace Lamar Johnson, who wasn’t asked to return next season. Gamboa, who was a bullpen coach with the Royals in 2001, will be replaced in the first-base coaching box by Luis Silverio, a coach, manager and scouting coordinator who has spent 28 years with the Royals.

Former bullpen coach John Mizerock will coach third base, replacing Rich Dauer.

Pitching coach John Cumberland and bench coach Bob Schaefer will retain their positions.
