It was very much a tale of two Smiths for Arizona this afternoon, as the first half of the split-squad doubleheader faces Seattle in Peoria. Caleb Smith was excellent, throwing five shutout innings, allowing just one hit, with three walks and three strikeouts. After a scoreless inning from Mitchell Stumpo followed, the D-backs had a 3-0 lead at the seventh inning stretch. Catcher Neyfy Castillo had given them the lead with a solo home-run in the second inning, and then drove in another run with a single in the fourth. Gavin Conticello made it 3-0 with an RBI single in the top of the seventh.
