Athletics lefty Rich Hill has a curveball that features an unusual amount of glove-side run. In last Friday's start against the Rays, Hill uncorked a breaking ball that was extreme by even his standards. Witness what he broke off on Brad Miller ...

And the people say: whoa.

Typically, you think of the curve as being more vertically oriented in terms of its break, but Hill's arm slot in tandem with the way he manipulates the pitch yields what you see above. And what you see above is a curve that's pretty singular in today's game.

You can probably guess that this particular offering is tough on same-handed hitters, which is why Hill this season has thrown it more than half the time against lefties. In this particular nine-pitch encounter with Miller, Hill went to the curve seven times.

Seriously, people, look at that thing.
