Alfonso Soriano
Bonds is the lone member of the 500–500 club, which means he has hit at least 500 home runs (762) and stolen at least 500 bases (514); no other player has even 400 of both. He is also one of only four baseball players all-time to be in the 40–40 club (1996), which means he hit 40 home runs (42) and stole 40 bases (40) in the same season; the other members are José Canseco, Alex Rodriguez, and Alfonso Soriano.
