For the most part, Brodie Van Wagenen's roster is set. However, within it, he'll need to make some decisions.
Third Base and Left Field
Jeff McNeil recently told the Daily News that he expects to play third base this season. I suspect this in large part is depended on what is happening this spring training in left field and if Jed Lowrie is healthy and productive.
In a world where J.D. Davis stumbles and Yoenis Cespedes isn't ready for action, McNeil may be needed back in left field, at which point Lowrie will need to take the hot corner.
