The others who turned the trick are Bob Horner, Chipper Jones, Eddie Mathews, Scott Rolen and Jim Ray Hart.
Yet Longoria doesn't see himself as a home run hitter.
"Sometimes it's kind of baffling to me that I hit as many home runs as I do," Longoria said, "because I go into batting practice, and I don't hit any home runs. On a very rare basis, I may hit one or two, but I'm really one of those guys who needs the pitcher to supply the power.
"I definitely have the kind of swing where I have to be in a good rhythm and feel good at the plate to be able to hit home runs. I feel like there are some other guys, namely Chris Davis, who is just so strong that his swing may break down from time to time. But he hits some balls, and maybe mishits them, and hits the ball out of the ballpark. There's a lot of guys like that."
Many of Longoria's home runs have been to the opposite field this season, which he said is an indication of "when I'm at my best."
