Adam Dunn is guaranteed $15 million next season and needs 64 home runs for 500 at age 33, but he may soon be done with baseball.

Dunn will consider retirement this winter if he decides that he is no longer enjoying the game.

"I'm not coming back just to come back for money or because I have one year left (on his contract)," Dunn said. "I'm not coming back to chase home-run numbers or whatever. If I end up with 499 and I'm not having fun, see ya — 499 it is."
