Even before the All-Star game, I added a post on my thread about Vaughn, Burger, Sheets and Mercedes that the Sox should move Moncada to 2B to open up 3B for Jake Burger's bat. I asked if it was an insane idea, but now I think more and more that it's the right move.
But during the All-Star game, when they interviewed Kris Bryant and showed how many games he'd played at 5 different positions, I thought that an All-Star player can in fact move around successfully.
Yoan Moncada has played 200 games at 2B. He's plenty capable of moving over there tomorrow.
Jake Burger, meanwhile, is a rookie, but he's off to a hot start after a torrid season in AAA, and looks like a much better hitter than Leury Garcia or Danny Mendick. One option was to try Burger at 2B, but that's a poor choice when Moncada can do that job much better.
Anyway, the final evolution in my thoughts about this would be for Moncada to volunteer to make the move. This eliminates any pressure to do so by the club, and keeps everyone happy. If he makes the move and Burger flames out or stops hitting, he can easily move back to 3B. He can even move back on a game-by-game basis. But if Burger keeps hitting, or improves, the Sox will be a better team, and Moncada will be seen as a selfless guy who only wants the team to win.
