When Sonny Gray dashed to cover first base, his left cleat remained on the pitching mound

There are a few things a pitcher needs with him on the mound: He needs his glove and the ball, obviously. He should probably be wearing his uniform, too. And he needs his cleats to keep his footing on the mound. Yeah, a pitcher definitely needs his cleats.

Sonny Gray knows.
In the fourth inning of the Twins' 4-0 victory over the A's on Wednesday, Gray jolted from the mound in an attempt to cover first base on Danny Santana's ground ball. He didn't get very far, though, as the dirt on the mound decided to keep his left cleat for itself, slipping it right off of Gray's foot. 
Santana reached first, and Gray had to take a moment to put his cleat back on without muddying his clean white sock -- he probably just did laundry, too. Doesn't that always happen?
And I don't know about you, but I'd start to keep an eye on these pitching mounds. They're up to something.
