In only three years in history have as many two players hit their 500th home run in the same season: 1967 with Mickey Mantle and Eddie Mathews, 1971 with Harmon Killebrew and Frank Robinson, and 2003 with Sammy Sosa and Rafael Palmeiro.
But this season, four players likely will hit No. 500: Frank Thomas (491), Alex Rodriguez (478), Jim Thome (477) and Manny Ramirez (475). If all four do, 10 members will have joined the 500 fraternity in 12 seasons after having only 14 in 120 seasons.
