This Aledmys Diaz grounder started out way foul and then had some other ideas
The ball rolled foul. Not "rolled toward foul territory" or "looked like it might roll foul" -- the ball left Diaz's bat at a 45 degree angle, and was ticketed for the on-deck circle. And then, well:
The Cardinals' offense was more conventional the rest of the game with five home runs.
Speaking to MLB.com's Jenifer Langosch after the game, Diaz seemed strangely nonchalant: "That's why you run hard out of the box," he said. "I thought it had a chance [to turn back fair]. You never know."
Oddity of physics, or proof that Aledmys Diaz is a wizard capable of bending space and time to his will? You be the judge.
