1. Catcher: Jonathan Lucroy (MIL)
    Next up: Wellington Castillo (ARZ), Yadier Molina (STL)... Lucroy has a team option for next year, after which he becomes a free agent, so he could be a really interesting trade piece for the Brewers. After a bad (and injured) 2015, he's back to his form of 2014, when he was among the most valuable players in the NL. Castillo played on three teams last year, was traded twice in three weeks, and now is making a legitimate case to be an All-Star. Weird.
  2. First Base: Anthony Rizzo (CHC)
    Next Up: Paul Goldschmidt (ARZ), Chris Carter (MIL)... Paul Goldschmidt is the best or second-best hitter in the National League, so consider him one good hot streak away from taking the starting spot at first. Chris Carter? This won’t last. He’s here because he has 13 homers, but that .299 OBP portends bad things and he’s been brutal ffor the last three weeks.
  3. Second Base: Daniel Murphy (WAS)
    Next up: Ben Zobrist (CHC), Jean Segura (ARZ)... All three are guys on new teams, with Murphy & Zobrist signing as free agents in the offseason and Segura getting to Arizona by trade. Zobrist has been tremendous for the Cubs. As good as Murphy has been, you can easily make the case for Zobrist here.
  4. Shortstop: Aledmys Diaz (STL)
    Next up: Corey Seager (LAD), Trevor Story (COL)... In the AL section, I mentioned how much more exciting the NL Rookie of the Year race is, with four solid contenders. Here are three of them, with Arizona’s Brandon Drury off to a terrific start as well. Unfortunately, Diaz has virtually no shot to start the game - he isn't on the ballot, so you've got to write him in.
  5. Third Base: Nolan Arrenado (COL)
    Next up: Kris Bryant (CHC), Brandon Drury (ARZ), Matt Carpenter (STL)... It’s hard to know where to place Drury, since he splits his time at third, second and left field. But he’s played most of his games at third. Kris Bryant has been very good, but Nolan Arrenado might be the best player in the NL right now.
  6. Outfield: Yoenes Cespedes (NYM), Bryce Harper (WAS), Ryan Braun (MIL)
    Next up: Dexter Fowler (CHC), Christian Yelich (MIA), Marcel Ozuna (MIA)... Cespedes, Harper & Braun are all established stars, but look out for Christian Yelich, Marcel Ozuna and Pittsburgh’s Gregory Polanco. Now, the thing that seems crazy is that while we think of Harper as “established” and the other guys as “young”, Harper is younger than all three of those guys. By the way, weird that Giancarlo Stanton has been healthy and he's the last deserving Marlin outfielder for the All Star Game.
