Yasmani Grandal and Yoan Moncada are probably the most excited.
Seriously though I guess I would be excited just purely due to our hitters will fare better. But I do have some concerns that similar posters on here have mentioned.
I think before the major shifting began, the most you had was the middle infield moving in for a double play, the 3rd baseman playing in for a bunt, the whole infield moving in to prevent a runner at 3rd from scoring, and everyone shifting to the right a bit for the lefties.
Where is the line drawn for these things?
