The first round of American League results were announced on Wednesday, and Bay led all outfielders with 446,183 votes. Josh Hamilton and Ichiro Suzuki round out the top three.
The Boston left fielder is vying for his third All-Star appearance, but first in the AL.
Nobody can question Bay's flair for the dramatic this season. He has been at or near the top of the league in RBIs in "close and late situations" through most of the season.

The Red Sox have plenty of other players in the running for a spot in St. Louis. Kevin Youkilis, who made the first All-Star appearance of his career last year, is in the lead at first base. Youkilis is having another terrific season as Boston's cleanup hitter.
Second baseman Dustin Pedroia, coming off his Most Valuable Player Award season of a year ago, is second in the balloting to Ian Kinsler of the Rangers. Pedroia started for the AL last year.
Sox third baseman Mike Lowell is fifth at his position, trailing Evan Longoria (Rays), Michael Young (Rangers), Alex Rodriguez (Yankees) and Scott Rolen (Blue Jays). Lowell, who has rebounded nicely from the right hip surgery he had at the end of the 2008 season, is a four-time All-Star.
Jason Varitek, the Red Sox's captain, trails only Joe Mauer (Twins) and Victor Martinez (Indians) at catcher. Varitek is a three-time All-Star.
Center fielder Jacoby Ellsbury, who has never made the All-Star team, is ninth in the outfield race. J.D. Drew, the Most Valuable Player of last year's All-Star Game at Yankee Stadium, is 13th among outfielders.
