Here’s a piece to get you set for Wang’s run at 7-0, a piece in the NY Sun by Tim Marchman, who I don’t link to often enough.

Here are the money shots:

For most of his time in the majors, Wang’s biggest weakness has been against left-handed hitters. Last year, for instance, he struck out 7.9% of those he faced, as against 17.8% of right-handers. There’s no mystery as to why. His nasty sinking fastball, which he routinely throws at 94 mph and can throw much harder, breaks down but also tilts — out and away from right-handers but right into the sweet spot where most left-handers like the ball. The same is true of his slider, his second-best pitch. Wang has usually tried to neutralize left-handers with a changeup that he rarely throws to right-handers, but it isn’t an especially effective pitch.

This year, he has slightly but noticeably changed his approach, throwing the fastball more often against left-handers and the changeup and slider less often, while mixing in the odd split-finger or cutter. So far, his strikeout rate against them is up to 12.2%, which isn’t fantastic, but represents an improvement of half over what he did last year. If he can keep doing as well while continuing to suppress left-handed power (he’s given up just one home run to left-handers in 82 plate appearances), he’ll have gone a long way toward plugging the biggest hole in his game. Against right-handers, Wang has been throwing a cut fastball a bit more often. It isn’t a great pitch, but it does give hitters something else to look for, and further shows his evolving style.
