OAKLAND — Josh Reddick became the first A’s outfielder in 27 years to win a Gold Glove, capping a debut season in Oakland that was more than anyone anticipated.

Reddick was named the American League’s best defensive right fielder in a vote by managers and coaches, beating out Kansas City’s Jeff Francoeur and Cleveland’s Shin-Soo Choo, the other finalists.

The A’s made the announcement Tuesday night just before ESPN2’s Gold Glove show hit the air. Reddick, excited to have won, paused his conference call with Bay Area reporters for a moment to watch when his name and picture flashed on the screen.

“It’s a true honor to be in this category with everybody,” Reddick said. “I’m just happy the A’s gave me the opportunity and I could pull it off for them.”

The A’s hadn’t had a Gold Glove winner at any position since third baseman Eric Chavez won in 2006.

Center fielder Dwayne Murphy was the last A’s outfielder to be honored back in 1985.

Reddick, 25, was the key acquisition from Boston last offseason in the Andrew Bailey trade. He showed fantastic range and a knack for the highlight play — whether it was scaling the wall for a catch or charging in to make a diving play. He finished third in the majors with 15 outfield assists — only Francoeur, with 19, threw out more base runners.

A’s outfield coach Tye Waller said he arrived at spring training not knowing what the team had in Reddick.

“I saw the arm strength, but the accuracy is what surprised me,” Waller said. “His ability to come in, go side to side was impressive. I had some concern that as a young guy in the league, he wouldn’t’ get attention. But he played a Gold Glove-caliber right field.”
