Quero is looking like the real deal. Moving to AA and looking stronger than ever means he's prime to rocket up the prospect lists. Some of his underlying numbers are very strong, BB% K% BABIP. If he keeps up his pace he will be a top 3 org prospect pretty easily soon.
These days for MiLB prospects I love to see low K rate, solid average, and if possible 5 to 10 HR per year which can often grow to 30 a few years into a MLB career so he checks all the boxes for me.
