Open Extended ReactionsWASHINGTON -- Philadelphia Phillies manager Rob Thomson said Thursday that he will use a six-man rotation beginning this weekend when Aaron Nola returns from the injured list. The National League East leaders also have ace right-hander Zack Wheeler, lefties Cristopher Sánchez and Jesús Luzardo, and right-hander Taijuan Walker. Thomson said he isn't sure how long he is going to use the six-man rotation. "Once for sure, and then we've got some other ideas how to attack this thing as we move forward," he said. Philadelphia starters lead the majors with 693⅓ innings pitched.
