Dontrelle Willis, the only 20-game winner in Marlins history, is coming off a 12-12 season, and trying to put some distance between himself and his first off-field incident. Willis, who was arrested for driving while under the influence of alcohol two months ago, said Sunday he didn't feel pressure to prove or redeem himself. ''Not at all,'' Willis, 25, said. ``I am going to continue to leave my heart on the field and hopefully that's enough. If not, then hey, I'm only going to do the best I can do. ``I'm not going to go out here and try to be Superman and climb fences and all that stuff. I'm going to continue to sign autographs like I did the year before and play hard like I did the year before.'' Clearly, he wants to put the incident behind him, and on the first day of scheduled spring training workouts, Willis expected to have to answer the predictable questions.
