The Marlins had the infield in with Chris Johnson at the plate. Sam Dyson induced a grounder to short, and Adeiny Hechavarria threw home. Catcher Jarrod Saltalamacchia ran Heyward back to third and flipped to third baseman Casey McGehee. The toss was high, causing McGehee to reach up to make the catch. Heyward was able to wiggle around McGehee's tag and return back to third base safely.
Redmond argued that Heyward went out of the baseline, but he never left the dirt path.
"I just thought he was out of the baseline," Redmond said. "I don't know. Maybe I was more frustrated that we didn't get an out in that situation, more than anything."
No error was charged on the fielder's choice. But it was a botched chance to get a sure out. Gerald Laird followed with an RBI single, scoring Heyward.
The ejection was Redmond's third of the season.
