Arizona at St. Louis

Arizona's pitching is vastly improved, tenth in the majors in team ERA (3.25). They've won two in a row as underdogs of +200 and +161 as well as five of the last eight. They just took two of three from the Dodgers, 5-3 and 3-1. Arizona starter Humberto Castellanos (3.00 ERA) comes off a 5-2 win over the Mets and faces a St. Louis offense that is #16 in runs scored, #17 in slugging. St. Louis has lost three of four, including as a favorite against the Reds, 4-1. Starter Dakota Hudson continues his comeback from Tommy John surgery, so back the undervalued visitors who are playing well. Take Arizona.
