The honor went to Minnesota Twins second baseman Brian Dozier, who earned his first career Gold Glove.
Kansas City first baseman Eric Hosmer received his fourth Gold Glove, while Angels shortstop Andrelton Simmons and Rays third baseman Evan Longoria each won their third.
The Royals were one of five teams that had two Gold Glove winners.
The award winners are determined by votes tallied from each Major League manager and up to six coaches on each staff, as well as the SABR Defensive Index, which comprises approximately 25 percent of the overall selection total. Diamondbacks ace Zack Grienke also picked up his fourth-consecutive Gold Glove after not making an error all season and conceding just five steals.
The ex-Husker continued to make some incredible catches in left field. Braves centerfielder Ender Inciarte and Red Sox right fielder both won their second-consecutive Gold Glove. The Royals are the only American League club to have at least one victor in each of the past seven seasons, while Colorado is the only club with a longer streak (eight-straight years).
Barnhart beat out two big stars in fellow finalists Buster Posey and Yadier Molina, becoming the first Cincinnati catcher to win since Hall of Famer Johnny Bench in 1977. "I'm a defensive guy, and I take a lot of pride in that", Barnhart said.
Each manager and up to six coaches on his staff vote from a pool of qualified players in their League and can not vote for players on their own team.
Hosmer played in all 162 games for the first time in his career, seeing action at first base in 157 of them, which led the American League.
