Phillies third baseman Placido Polanco, Reds second baseman Brandon Phillips and Cardinals first baseman Albert Pujols also continued their reign as the top vote-getters at their respective positions.
Pujols (2,081,590), who leads reigning NL MVP Joey Votto (1,773,348) for the top spot among first basemen, joined Braun as the only NL players to have received more than two million votes.
Among the catchers, injured Giants backstop Buster Posey dropped to third in the voting, while St. Louis' Yadier Molina moved into the second spot behind five-time All-Star Brian McCann. The 27-year-old Braves catcher took home MVP honors at last year's Midsummer Classic.
Los Angeles' Andre Ethier and Matt Kemp, who owned the fourth- and third-best batting averages in the league (.331 and .321, respectively), are fourth and fifth in the outfield voting. The NL's Player of the Month for May, Cincinnati's Jay Bruce, is sixth.
