McDonald is an all-bat prospect with very little margin for error; he demonstrates a solid approach at the plate, commanding the zone well and attacking decisively when he commits. He has shown commendable growth in toning down some of the early season noise in his swing, better engaging his lower half as the year has progressed and making the swing less dependent on raw strength. The power he has should play, but I worry about his ability to consistently handle high-octane velocity on the inner half.

Very limited defensive profile leaves him best-suited as a DH prospect, putting enormous pressure on the hit/power combination to max out. Low-impact player may provide some value as a power bat on the bench or a second-division DH if he hits his ceiling in the batter's box.
