Philip Humber threw the 21st perfect game in baseball history, keeping every single Mariner off the bases on Saturday. But there was just a teensy bit of controversy with the last out:

Brendan Ryan thought he checked his swing and started walking to first, but he was rung up by home-plate umpire Brian Runge. Was it a swing? It's hard to tell, but I'm going with "probably not." But it was definitely close enough to call without creating a huge controversy. There's a pretty good chance that Runge was thinking "Don't pull a Jim Joyce don't pull a Jim Joyce don't pull a Jim Joyce" for the last inning.

The most important thing that we're missing here is that it would have been awesome if Ryan had reached on a dropped third-strike. Perfect games are rare -- only 21 in baseball history -- but you know what's even rarer? Perfect games that are lost on dropped third-strikes. As is, it's still pretty cool to see a perfect game.
