Cubs activate Castillo, option Maine to Iowa

CHICAGO -- The Chicago Cubs made it official before Saturday’s game, activating Lendy Castillo from the disabled list and optioning left-hander Scott Maine to Triple-A Iowa.

Castillo has been out since May 11 with a left groin strain and just completed a lengthy minor-league rehab assignment.

In seven outings earlier this season, the right-handed Castillo had a 7.40 ERA. Maine is 1-1 with a 4.79 ERA over three separate stints with the Cubs this season.

Castillo was a Rule 5 selection from the Phillies this past winter and must be on the major-league roster all season or be offered back to his former club.
