Vance Worley is 12-5 with a 2.86 ERA and 8.2 K's/9 in 26 career starts, yet he is owned in less than half of ESPN.com fantasy leagues. What gives? Granted, he hasn't faced top lineups this season (San Diego Padres, New York Mets and Pittsburgh Pirates), but a 2.37 ERA and 21 K's in 19 innings is pretty impressive no matter the competition. Expect more missed bats Monday, as the Arizona Diamondbacks have the fourth-most strikeouts in the majors (8.2 per game). Also, Josh Collmenter, who has been arguably the worst starting pitcher in baseball this young season, is opposing Worley on the hill. Collmenter's 10.22 ERA and four home runs allowed in 12 1/3 innings is only slightly better than Francisco Liriano's 11.02 ERA.
