Jeff Locke pitched scoreless third and fourth innings Thursday in the Pirates' 8-2 victory over the Yankees. Locke, an NL All-Star last season, is fighting to make the rotation this spring. As things stand now, Edinson Volquez is likely the favorite for the fifth spot. However, that assumes Wandy Rodriguez is healthy. There's a good chance Rodriguez will wind up on the DL, leaving room for both Volquez and Locke.
