As we wind down the fifth of six months in the fantasy baseball season, owners should be looking at recent statistical trends rather than full-season numbers, and several pitching performances from Tuesday night remind us how quickly things can change. For example, the Pittsburgh Pirates and New York Mets were joined Tuesday by a trade that sent Marlon Byrd and John Buck to the contending Bucs for a prospect. Later that evening, the teams' left-handed starting pitchers continue to show they’re heading in different directions. The Pirates’ Jeff Locke was an NL All-Star last month and ERA leader. The Mets’ Jonathon Niese had a high ERA and a partially torn rotator cuff. On Tuesday, Locke was pounded yet again while Niese spun a three-hit shutout. Who’s owned in more leagues?
