Los Angeles Angels right-hander Bartolo Colon won the American League's 2005 Cy Young Award for the best pitcher.
Colon's injury hampered the Angels' World Series hopes
Colon, the AL's only 20-game winner, got 17 first-place votes and 118 total points to become the Angels' first Cy Young winner since Dean Chance in 1964.
Colon was the only man named on all 28 ballots by members of the Baseball Writers' Association of America.
The award goes to the top pitcher in each league. The National League winner will be announced on Thursday.
New York Yankees reliever Mariano Rivera finished second with eight first-place votes and 68 points. Minnesota Twins left-hander Johan Santana, last year's winner, was third with 51 points.
Colon, a 32-year-old from the Dominican Republic, won 21 games against eight losses. He had a 3.48 earned run average, the league's eighth best.
He strained his right shoulder in the fifth game of the AL Division Series with the New York Yankees last month and did not play again this year.
The Angels beat the Yankees but were eliminated by the Chicago White Sox, the eventual World Series winners, in the American League championship series.
"After the season, I've been thinking about it a lot, and one of the prevailing thoughts was the fact that maybe I won't get it," said Colon, who earned a $500,000 bonus for winning the award.
"Maybe it was going to go to somebody else. A lot of crazy things came into my head."
The Cy Young Award is named after the only pitcher in the first 100 years of Major League Baseball to win 500 games.
