Pettitte isn't that great a prospect, as he's old for the level, but New Hampshire starter Zach Stewart was extremely impressive in his seven innings of work, striking out 10 (also against a weak lineup) with just one walk and ten groundouts against just one air out.
Stewart showed four pitches, pitching at 90-96 with sink and some tail with a tight, out-pitch slider at 83-87 that he threw for strikes, even back-dooring it to left-handed hitters for called strikes. His changeup was the biggest surprise, as another scout at the game told me he hadn't seen it this good before; it's mostly straight but has good separation from the fastball at 81-85 and his arm speed is excellent. He also used a fringy curveball with good depth, but he didn't command the pitch as well as he did the slider.
Stewart worked aggressively with everything and had good tempo. He stays over the rubber before driving forward with a long stride, although his arm action is a little long in the back and he pronates relatively late in the delivery. I know several scouts see Stewart as a sinker/slider pen guy, but I see four pitches, a good frame, and a pitcher who likes to attack hitters, and I see a potential No. 2 starter, maybe a No. 3 if the changeup isn't always where it was tonight.

It was a weak lineup, but good news is good news right?
