Cespedes, 27, has 38 home runs in his first 206 MLB games. This year, he is averaging a home run every 20.1 at-bats and has 15 big flies in 77 games.
On Saturday, while taking a practice round for the derby, Cespedes was mashing home runs. He hit one into the "O" in the O.Co sign in left field, which teammate Josh Donaldson did in early June.
