The meaning of “That’s what speed do.”
You’re probably hearing Royals fans say, “That’s what speed do” a lot. With games on the line, they tend to slap the ball, get on base however they can, and score however they can, and that’s what the line refers to.
The origin was a game on July 27, 2013. Jarrod Dyson led off the 12th inning with a ground ball to Gordon Beckham, who bobbled the ball. The scorekeeper credited Dyson with a controversial single.
“That’s a single,” Dyson insisted after the game. “That’s a tough play. That’s what speed do. If you can’t handle the ball, put it back in the glove.”
Dyson knows speed. He once tagged up and scored the game winning run on a popup to shortstop.
