At first base, Anthony Rizzo leads by 1.4 million votes and is the leading N.L. vote-getter.
Ben Zobrist has a 300,000-vote lead over Daniel Murphy of the Nationals at second base
Kris Bryant has a similar lead over Colorado's third baseman Nolan Arenado.
And Dexter Fowler remains the top outfield vote-getter, but less than 100,000 votes ahead of Bryce Harper. Fowler's reasonably certain of remaining in the top three, as he, Harper and Yoenis Cespedes are all at least 700,000 votes ahead of Jason Heyward, who's fourth. (Yes, it's a popularity contest, as you surely know.)
