Jeff Francis and Rodrigo Lopez have been the surprising driving forces to our recent run, as they've been as solid a pair of #2 and #3 starters in the majors over the last month. Tonight, Francis tries to extend his run of success against a dangerous Yankees lineup that nonetheless has trouble against LHP's, being 8-10 overall in starts by left-handers. That said, the Rockies have had more trouble against southpaws this year, going 6-12 when the opposition has started one. Andy Pettitte is still one of the best LHP's in the majors, and this won't be an easy contest. Let's scratch out the victory and win another series.
