Confidence game: Admit it. You were starting to wonder about Jake Arrieta (pictured) after he blew up in that game in Anaheim a couple of weeks ago and then lost to the Oakland A's last Friday. He hadn't won since Opening Day and he was facing a particularly difficult test against Ivan Nova and the Yankees on Wednesday night. Apparently, he's a big-game pitcher, because he dominated the Yankees and snapped Nova's 15-game winning streak. Coming on the heels of a very uplifting performance by Brian Matusz the night before, the confidence of the Orioles rotation has to be sky high right now.
