CHICAGO (AP) The Cincinnati Reds have dismissed pitching coach Mark Riggins, hoping to shake up a staff with the worst ERA in the majors.

Riggins was in his first season after spending the previous four years as the organization's minor league pitching coordinator.

But with a 5.51 ERA and a 30-53 record entering Monday's game against the major league-leading Chicago Cubs, the Reds decided to make changes. Assistant pitching coach and bullpen coach Mack Jenkins replaces Riggins. Triple-A Louisville pitching coach Ted Power will assume Jenkins' role.

President of baseball operations Walt Jocketty says he hopes Riggins will remain with the organization in some capacity. He credits Riggins for helping develop young pitchers in the minors but points to a lack of improvement at the major league level.
