Miami ? Rookie sensation Dontrelle Willis achieved two impressive feats Wednesday night. First he helped the Florida Marlins fill Pro Player Stadium, and then he beat Randy Johnson.

Willis had a little help from Arizona second baseman Junior Spivey, who made an errant throw that allowed two runs to score in the sixth inning. That was the difference as Willis and the surging Marlins beat Johnson and the slumping Diamondbacks 3-1.

The showdown of showcase left-handers drew a crowd of 37,735 — much more than the Marlins projected, and their largest turnout since July 14, 2001. Nearly half the tickets were purchased Wednesday in anticipation of a pitching gem, and that’s what the fans got.

“If you’re not a fan of baseball watching that game, you’re not going to be a fan,” Willis said. “It was just fun to watch.”

The crowd also saw the Marlins win their sixth game in a row and complete their first-ever series sweep of Arizona. The Diamondbacks have lost nine consecutive road games, a team record.

In a battle of the ages, the 21-year-old Willis (10-2) gave up four hits in seven innings. The only run scored by the D-Backs against the D-Train was a homer by the second batter he faced, Alex Cintron.

The 39-year-old Johnson, making his third start after missing 2 1/2 months following knee surgery, was almost as good. Johnson (1-4) allowed four hits in six innings but gave up two runs — both unearned — in the pivotal sixth.

Johnson lost to the Marlins for the first time in 10 career starts against them. Asked how he felt about his performance, he replied, “I’m pleased.” When reporters paused before asking another question, he said, “All right, that’s it,” and left.
