NEW YORK -- Back in the minor leagues, Brandon Webb had so much trouble controlling his sinker that he was hitting batters with it all the time and growing increasingly frustrated on the mound.

A few years later, that sensational pitch made him a Cy Young Award winner.

The Arizona Diamondbacks' ace won a wide-open race for the National League's top pitching honor, beating out San Diego closer Trevor Hoffman yesterday.

"It's really unbelievable, looking back to where I started from," Webb said. "It just happened for me this year."

One of six starters who tied for the league lead with a pedestrian total of 16 wins, Webb received 15 of 32 first-place votes and 103 points in balloting by the Baseball Writers' Association of America. Hoffman, who broke the career saves record this season, got 12 first-place votes and 77 points.

St. Louis Cardinals ace Chris Carpenter, last year's winner, finished third with two first-place votes and 63 points.

"All three of us probably were deserving of it and probably a couple more guys, too," Webb said. "I knew that I had a pretty good chance."

Houston's Roy Oswalt, who led the NL with a 2.98 ERA, got the other three first-place tallies and came in fourth.

Webb, who went 16-8 with a 3.10 ERA and made his first All-Star team, was listed second on seven ballots and third on seven others. No pitcher was included on every Cy Young Award entry.

"It was pretty big emotions. We were very excited for it," Webb said. "It's with you forever. To have that title go along with you means a lot."

Webb's victory total was the lowest for a starting pitcher who won the Cy Young Award in a full season. The previous low was 17 wins, by Pedro Martinez of the Montreal Expos in 1997 and Randy Johnson for Arizona in '99.

Fernando Valenzuela of the Los Angeles Dodgers was honored with a 13-7 record in 1981 and Atlanta's Greg Maddux went 16-6 in '94 -- but those seasons were cut short by players' strikes.

"A lot of the wins pitchers can't control," Webb said. "You can give up one hit and still lose the ballgame."

Webb also is the first NL winner to have an ERA above 3.00 since Philadelphia's Steve Carlton had a 3.10 mark in 1982. Rick Sutcliffe split the 1984 season between Cleveland and the Chicago Cubs, finishing with a 3.64 ERA overall but a 2.69 mark in the NL.

Webb's success came only two years after he really struggled.

After a strong rookie season in 2003, Webb walked a major league-high 119 batters the following year for a terrible Arizona team that went 51-111. The right-hander also led the NL with 16 losses and 17 wild pitches that year.

But he cut his walks in half in 2005 and issued a career-low 50 free passes this year. And he got more help from Arizona's much-improved infield defense.

"Basically, I just tried to do what I've done the last three years, which is throw a lot of sinkers," Webb said.

Before Webb, Johnson was the only Diamondbacks pitcher to take home the award, winning four consecutive times from 1999-02.

Webb threw a career-best 235 innings, which ranked second in the NL. The 27-year-old sinkerballer also tied Carpenter for the league lead with three shutouts and both had five complete games, good for second in the NL.

The AL Cy Young Award winner will be announced tomorrow-- with Minnesota's Johan Santana is a heavy favorite.
