ANAHEIM, Calif. — If the Red Sox are to extract any value out of the trade that sent Kevin Youkilis to the White Sox, it’ll be up to Zach Stewart to provide it.

The righthander will get a chance to show his worth Wednesday night when he starts against the Los Angeles Angels. With lefthander Franklin Morales going on the disabled list with a sore shoulder, Stewart is the latest pitcher to join the rotation.
