Hit	50	Easy swing and excellent all-fields approach, often waits back and looks to drive ball the other way; good approach on spin. Can look a bit grooved at times though; definitely the swing of a power hitter. Better high-ball than low-ball hitter in my looks and tries to lift. There's some swing and miss with his fairly long levers and he could probably work the count more.
Power	60	Real pop to all fields that already plays in game; has natural strength and good bat speed along with some loft to the swing. This is his main asset that he will need to maximize as he refines his hit tool. He will be able to tap into his power even more with improved plate discipline.
Baserunning/Speed	40	Average at-best runner despite frame and the athleticism he shows elsewhere.
Glove	50	No real worries with his defense, even if he doesn't wow you with it. Makes all the routine plays.
Arm	55	Definitely strong enough to handle third, and the most impressive asset he has defensively.

It is possible I'm overstating the case a bit, but I believe some of the ambient handwringing around Vientos is unnecessary. He is fine at third base, and he has at least plus power and should grow into more. He will need to refine the hit tool, preferably lowering strikeouts slightly and improving his selectivity at the plate which would add to his overall offensive value in multiple ways. Excited to see how he adjusts to the higher levels, where he will still be on the young side.
