Last night, Madison Bumgarner finally found a groove, tossing seven scoreless innings en route to a 2-0 Giants victory. You’ll hear a lot — or, scratch that, have probably already heard a lot — about how Bumgarner didn’t have his best stuff last night, and I think that’s pretty fair to say. Despite the mechanical adjustments he made prior to the outing, his fastball didn’t gain any zip, and his slider was certainly not at its best. When Bumgarner is at his best, he’s touching 93 with the fastball, and he’s throwing the slider with considerably more velocity and movement.

But Bumgarner had no trouble shutting the Tigers down yesterday, as he limited them to two hits in total while also racking up eight strikeouts. His last time out, he’d struggled to get the Cardinals to swing and miss at his stuff. In total, he only managed five swinging strikes. Last night, though, Bumgarner more than doubled that, yielding 12 swinging strikes in all. This might, as Jeff Sullivan suggested, have something to do with increased differentiation between his fastball and slider. The charts on Brooks Baseball (10/14, 10/25) make this pretty noticeable. For example, check out the horizontal movement of Bumgarner’s pitches plotted against the velocity. In his NLCS start, the pitches were somewhat clustered together, whereas there was a clear distinction in last night’s start. I tend to avoid jumping to conclusions based on pitch f/x numbers because it’s very easy to get misled, and I’m no expert on this stuff, but I’d have to think this is a pretty good sign.

Maybe Bumgarner’s stuff was “bad” last night, but if that’s the case, it’s a testament to how damn good he is. A pitcher can’t luck his way into eight strikeouts over seven innings of two-hit ball against one of the better offenses in baseball. Nope. That’s not to say that Bumgarner didn’t encounter some luck last night — he got away with some mistake pitches, and had some help from the defense — but there was definitely more to it than that. Something was working for Bumgarner, and while it remains to be seen whether he can recapture that magic if he does happen to make another start in this series, Bumgarner was dominant last night.

The Giants are two victories away from a championship, by the way.
