Desmond Jennings figured his unassisted double play in Saturday's third inning was something that doesn't happen often.

But neither the centerfielder nor the rest of the Rays realized how rare it was.

"I thought it might have been the first one ever in the world," manager Joe Maddon said.

Though it wasn't a world first, Jennings became the first Rays outfielder to complete the feat, and the first big-league centerfielder in more than 20 years to do it in this fashion.

With one out and Athletics 2B Eric Sogard on first base, Jennings raced in to catch a fly ball by CF Coco Crisp. Jennings then looked up and saw Sogard had already run to third, thinking the ball was going to drop in.

So Jennings jogged over and tagged first base on his way to the dugout for the final out.

"I was already heading in that direction," Jennings said, smiling. "So why not?"

The last centerfielder to complete an unassisted double play by catching a fly ball and physically recording the putout at first base was the Pirates' Andy Van Slyke on July 7, 1992, against the Astros, the Elias Sports Bureau said.
