Cardinals manager Tony La Russa said Friday that Kyle McClellan could be left off the NLDS roster against the Phillies. McClellan is dealing with arm fatigue, which is perhaps an explanation why he posted a 7.71 ERA and 6/6 K/BB ratio over 11 2/3 innings this month. We should learn the full composition of the roster soon, but Jake Westbrook is expected to pitch out of the bullpen.
