The Dodgers shift Mookie Betts the other way on the defensive spectrum:

Speaking on the MLB Network on Monday, Roberts put to the rest the notion of Betts part-timing in both the infield and outfield as the Dodgers look to win the National League West for the third year in a row.

“It’s pretty safe to say that No. 50, Mookie Betts, is going to be our every-day second baseman,” Roberts said.

Betts, 31, was the Dodgers’ second baseman against righties last year. But second base is Betts’ preferred position, and he thought it’d be easier to stick to one position. The Dodgers also believe that playing second base is easier on his body.

That last bit goes against what I’ve always thought, that middle infielders get banged up a bit more than outfielders, due to the collisions at second base on double plays and caught stealing. The rules have changed to make interactions between those fielders and runners safer, but accidents still happen. From the defensive spectrum link above:

The basic premise of the spectrum is that positions on the right side of the spectrum are more difficult than the positions on the left side. Therefore, the positions are easier to fill as one goes left on the spectrum, since the physical demands are less.

So this is a bold move by the Dodgers, especially since Betts is already past his prime years. Certainly, Betts’s offense is more valuable at second base, and if he is successful at the position it will be another positive tick in his Hall of Fame case.
