As manager As coach Anthony Joseph Muser (/ˈmjuːzər/; born August 1, 1947) is an American former professional baseball player, who currently serves as a roving instructor in the San Diego Padres organization.

After being replaced by John Mizerock, Muser spent four seasons as the bench coach for the San Diego Padres under Bruce Bochy.

After batting .260 during the first 2+1⁄2 months of the campaign, Muser was acquired by the Orioles from the White Sox for Jesse Jefferson in one of two transactions made by Chicago at the non-waiver trade deadline on June 15, 1975.

In 1980, Muser was brought back into the Brewers organization, as he was hired as manager of the Stockton Ports, one of Milwaukee's A-ball farm clubs.

In 1993, Muser moved to the Chicago Cubs, where he served as their hitting coach until 1997, when he was named manager of the Kansas City Royals.
