In results released on Monday, Phillips stayed in fourth place among NL second basemen while Mesoraco was in fifth place among catchers.
Phillies second baseman Chase Utley led the position with 1,342,480 votes. Utley was followed by the Dodgers' Dee Gordon (735,831 votes), Neil Walker of the Pirates (614,273) and Phillips with 441,076 votes.
Behind the plate for the NL, Cardinals perennial All-Star Yadier Molina held a commanding lead with 1,621,944 votes. Molina was trailed by Buster Posey of the Giants (1,078,007 votes), Jonathan Lucroy of the Brewers (771,313) and Evan Gattis of the Braves (565,620), while Mesoraco (418,422) rounded out the top 5.
All voting results are combined totals from fans who vote online at MLB.com and in-stadium balloting.
Phillips is seeking his second-straight All-Star game start and fourth trip overall. Mesoraco, a first-time regular in Cincinnati's lineup, is seeking a first-time bid.
Phillips came into Monday's game batting .269/.305/.393 with four home runs and 22 RBIs in 59 games. Mesoraco, who was given a day off Monday while mired in a career-high 0-for-17 skid, entered batting .305/.352/.609 with nine homers and 27 RBIs despite two stints on the disabled list that have limited him to 33 games.
"I didn't think he was going to hit .475 all year," Reds manager Bryan Price said of Mesoraco. "I never was with Tony Gwynn or George Brett or those guys or Wade Boggs, but I was with Ichiro [Suzuki]. It was maybe a .380 month followed by a .280 month. In the ebb and flow of the game, it's hard to maintain that level."
