His strikeout rate had been steadily increasing over his last two starts with 13 of his 18 strikeouts coming over that span. But his inability to pitch deep into games continued to haunt him. In five starts, Gonzalez never threw more than five innings and threw less than that three times.

Gonzalez will likely head to Durham, NC., to meet up with the IronPigs for the start of their seven-game road trip.
