With the balloting process concluding on Thursday night, McCann has further widened his lead over all NL catchers. The 26-year-old has garnered nearly 800,000 more votes than the Cardinals' Yadier Molina, who ranks second in this group.
Molina was elected the NL's starter in each of the past two years. But as long as McCann continues to draw support over the next couple of days, the Braves backstop would be in line to secure this year's top spot, having led all NL catchers in batting average (.300), on-base percentage (.379), slugging percentage (.512) and home runs (13) entering Monday.

It appears McCann will be the only Braves player elected to start this year's All-Star Game. Chipper Jones ranks second among NL third basemen but stands more than one million votes behind the Phillies' Placido Polanco.
Shortstop Alex Gonzalez and second baseman Dan Uggla also stand more than one million votes behind the leaders at their respective positions.
Braves right fielder Jason Heyward was elected to serve as one of the NL's starting outfielders when he was just 20 years old last year, but he has struggled through an injury-plagued season in 2011 and ranks ninth in this year's NL outfield race.
Rookie first baseman Freddie Freeman still ranks fifth at a position filled with superstars. Each of the players positioned in front of him -- Albert Pujols, Prince Fielder, Joey Votto and Ryan Howard -- has garnered more than one million votes.
