Wilson gets the bulk of the credit -- he pitched 7.1 innings and struck out nine, walking just two. Diaz pitched two-thirds of an inning, and Slaten pitched the ninth.
Wilson has alternated terrible starts with brilliant ones so far this season. He walked six and struck out six in his 2012 debut on April 6, then had seven strikeouts and no walks in his next start. Two starts later, he was back to five walks and five strikeouts. He clearly knows how to strike batters out, so it'll be interesting to see if he can become more consistent with his control. If he does, he could still be a decent big-league starter. If not, he's probably destined for the bullpen.
