LOS ANGELES -- Zack Greinke politely refused to talk about it, shaking his head and smiling before he walked off.Los Angeles Dodgers manager Don Mattingly wouldn't offer much more detail about whatever is ailing Greinke's pitching elbow.Asked if Greinke would make his scheduled start Thursday, Mattingly said after the Dodgers' 8-6 win over the San Diego Padres, "It's nothing that we would talk about right now. It's a possibility."So, there is a "possibility" that the Dodgers' second-best pitcher will be healthy enough to stay on his regular turn in the rotation.
