You can’t always take too much out of stats from the Summer Leagues due to all of the factors. These players are at a very young age, the competition isn’t always the best, and it is a very small sample size. Even with all those factors, it is still hard to not notice what Brandol Perez did in the Dominican Summer League last year.
Perez is at the very young age of 17. At the time he was playing in the league, he was only 16. Over the course of 48.1 IP, Perez had an ERA of 0.19. He gave up 3 runs and only one of those was earned. He also struck out 68 batters, giving him a K/9 of 12.7! His walk numbers suggest decent control at that age. He walked 14 batters, a BB/9 of 2.6. One more stat that really catches your eye is that Perez did not give up a single homerun. Perez made 11 appearances over the course of the year. He started 6 games and the other 5 appearances were out of the bullpen. If you thought those stats look good you will love his build.
Perez is a 6’4” 175lb lefthanded pitcher. He is still only 17 so there is plenty of room to grow even taller and bulk up. His frame suggests a lot of projectability down the road. Jason Churchill of prospect insider ranked Perez as the top Mariners Latin American Prospect in the Summer Leagues from last year. His arsenal consists of a fastball, slider, and curveball and he is developing a changeup. His fastball sits in the mid 80s and his velocity will increase as he develops.
Churchill states that “Perez grinds it with runners on base, a sign of maturity, and has a solid pickoff move. He's also a good athlete and fields his position well. His control and command are slightly below average, but that's typical for most 16 and 17-year-olds, foreign or domestic”
It’s great to see that Perez is showing an aggressive presence on the mound. He still has a long road ahead of him, but he is already showing maturity at a young age as Churchill pointed out. Perez could become a big aggressive lefthanded starting pitcher which all organizations love to have! Perez is a name to watch in the coming years as he continues his development.
