C Yadier Molina
Really close call between him and Buster Posey, who's hitting as well as he did last year, but Molina's been even better.
1B Paul Goldschmidt
Another tough choice between him and Joey Votto, who can't touch Goldy's power numbers but is still a better pure hitter. Can't go wrong with either one, but bWAR says Goldschmidt has been a bit more valuable than Votto, and I have to agree.
2B Matt Carpenter
Fans might be compelled to go with more recognizable names such as Chase Utley or Dan Utley, but Carpenter is the clear-cut choice here with his Dustin Pedroia-type season.
3B David Wright
Overshadowed by teammate/wunderkind Matt Harvey, Wright is quietly putting together another tremendous all-around season to add to his ledger.
SS Troy Tulowitzki
Ian Desmond and Jean Segura (the NL hits leader) have been stellar, just not as good as Tulo, who was on his way to an MVP-caliber season before landing on the Disabled List in mid-June with a broken right-rib. Segura should be the one to replace him.
OF Carlos Gomez
The second most valuable player in the Senior Circuit (behind only Clayton Kershaw) according to bWAR.
OF Carlos Beltran
Beltran's been a force for the Cardinals this year and is a big reason why they have the league's second best record.
OF Carlos Gonzalez
The league-leader in runs, homers, and total bases has done everything possible to keep Colorado afloat in an extremely competitive NL West. Surprisingly his numbers are better on the road (.976 OPS) than they are at Coors Field (.959 OPS).
