"Pablo [Sandoval] hit a ball in the gap, a low liner, that I got my glove just low enough to catch," Gwynn said.
Gwynn has made a habit of big catches this season. Gwynn currently has the second-best UZR rating (ultimate zone rating) in the Major Leagues, 12.3. He trails Carl Crawford of the Rays (15.2).
UZR is the number of runs above or below average a fielder is in range runs, outfield arm runs, double play runs and error runs combined.
Gwynn said his preference is not to leave his feet.
"I've done enough of those," he said. "I really don't want to dive. There is a less risk of hurting yourself if you don't."
San Diego manager Bud Black was certainly impressed by Gwynn's catch.
"Another highlight-reel catch," Black said. "That was a tough one. It looked like it was hooking or knuckling."
