Scott Van Slyke left Wednesday night's game against the Arizona Diamondbacks with what the Los Angeles Dodgers called a mild right ankle sprain.
He later blamed the Diamondbacks' grass for the injury.
"They've got bad grass here," Van Slyke said.
Van Slyke said the ground gave way beneath his ankle as he planted to throw. Replays showed that Van Slyke's ankle bent to almost a 45-degree ankle.
"That side of my ankle's loose, so I think it will be all right," he said. "I think it just went further than it normally does."
