The next Tyler White?
He has a better glove than White, but I would not expect him to match White's offense numbers. A quick comparison at level:
Class A
White (23; 2014) 71 G, 290 AB, 20 2b, 7 HR, 35 BB, 40 K, .305/.414/.485
Tanielu (22; 2015) 110 G, 419 AB, 27 2b, 6 HR, 30 BB, 65 K, .308/.354/.434
Class A+
White (23; 2014) 43 G, 186 AB, 13 2b, 8 HR, 28 BB, 27 K, .267/.403/.527
Tanielu (23; 2016) 21 G, 80 AB, 6 2b, 2 HR, 5 BB, 13 K, .300/.345/.475
I think the K-rate, K:BB ratio and HR rate are most telling.
