Second Base: Daniel Murphy vs Ben Zobrist
Zobrist has always been a fine player who can hit, provide some power, and still provides versatility in the infield, but he is going against the hottest hitter in the postseason in Murphy, who has put up ridiculous home run numbers in the playoffs.
Like Zobrist, Murphy can also play multiple positions around the infield. Zobrist has had his playoff moments like the home run he hit off David Price in Game 6 NLCS. But Murphy is on another world now, hitting-wise, in the playoffs to go with his NLCS MVP.
