The others are Eddie Mathews, Mike Schmidt, Ron Santo, Chipper Jones, Bob Horner and Matt Williams.
"Thirty is pretty solid," Rays manager Joe Maddon said. "Thirty home runs these days really represents some pretty good power. So, yeah, I think it's outstanding, and that's even with a really tough month, month and a half. It's been unusual to see him struggle ... and still be able to put up those kinds of numbers. He's a unique player, that ball he hit last night was properly struck. But this is the kind of thing he can do on an annual basis. And he's going to keep getting better."
Maddon smiled when it was called to his attention that Longoria does not consider himself a home run hitter.
"I understand why he says that, because he really works on other things offensively," Maddon said. "He's got home run power, no question. And when he gets the ball up in the air, it just keeps going. I like the fact he's more concerned about being more of a technician, or a better hitter, and letting the power just show up."
