Right-hander Jonathan Pettibone walked three and fanned four in the 103-pitch, three-hit effort.
With the win, the 22-year-old righty improved to 4-0 with a 1.69 ERA in five starts since joining the Triple-A IronPigs. Between Lehigh Valley and Reading, he's 13-7 with a 2.95 ERA. Pettibone rated as Baseball America's 4th best prospect prior to this season and has been making a steady climb through the system. He could be an option for the Phillies' rotation as early as next season. Next February would mark his first spring training with the big club, where he could audition alongside teammate Tyler Cloyd, who would be another newcomber.
The win, which occurred in the opener of Tuesday's doubleheader, moved the IronPigs into the Internaitonal League Wild Card lead.
