Carrasco, Mayberry optioned to minors

The Phillies have optioned pitcher Carlos Carrasco and outfielder John Mayberry Jr. to the minor leagues.

Carrasco's demotion crystallizes the battle for the fifth starter spot between J.A. Happ and Chan Ho Park.

Second baseman Marcus Giles was released. Giles was attempting to make a comeback after spending last season out of baseball. The pace of Chase Utley's recovery likely made Giles expendable.

The Phillies also told reliever Mike Koplove, a South Philly native; outfielder Jason Ellison; and veteran infielder Pablo Ozuna they will not make the team, but the three will accompany the team north for the weekend exhibition series at Citizens Bank Park.
