Hamilton vs. Campana
So reader Virginia Phil had the idea to try and time the inside-the-park home run of speed phenom Billy Hamilton with that of Crazy Legs Campana from last year. By his not-quite scientific standards, Hamilton just edged out Campana by a tenth of a second.
Reader Black Earthling took it a step farther and synced the two videos for the definitive video proof.
I don't think you'll find anyone in baseball that believes Campana is as fast as Hamilton and you can see in the video Hamilton stumbling just a bit approaching second and what looks like some wide turns at second and third base that you don't see Campana taking from the wide shot and less camera time he's granted. But maybe Campana is just a better at those type of things which ultimately contribute to overall baserunning speed, although I certainly wouldn't point to this one clip as the definitive proof. And as noted by both readers, Hamilton slows up at the end once he realizes he'll be safe. But it's certainly closer than I thought it would be and makes for some fun triviality before tonight's Marlins/Cubs game.
