2014 Baseball America preseason prospect handbook notes:
Escobar (2)
"....Escobar always had size and strength, but he got himself in better condition and made an adjustment to raise his elbow in his delivery, allowing him to locate his 92-93 mph fastball, and for the first time, throw a dependable breaking ball. He gained confidence in his slider and it's a plus offering at times that he can throw early in the count or as a put away pitch. His changeup also ranges from average to plus, and he held righthanded hitters to a .222 average..."
Hembree (7)
"Expected to be the club's closer of the future...Hembree vaulted up the prospect rankings because of his 98 mph fastball and power slider. He pitched more effectively in the 92-94 mph range in 2013, but has addressed past issues of wildness within the strike zone and shows more ability to dial back and locate....Even if he never gets back that 98 mph heat, his size and stuff compare well with former Giant Bob Howry...."
