Counting the Top 10 throwers of the last 10 years.
#4 Adam Hajdak
This rest of this list is about to get contentious starting now.
Adam has gone through one of our biggest transformations the last 5 years, most of which was on his own time. One of our hardest workers, Adam went from a 14u kid with inconsistent outings, a caving lower half and choppy arm action to one of our hardest and most consistent HS throwers topping off at 93 this past winter. One of the biggest factors from an outsiders perspective was playing dogs like and even . Shoutout joe pie.
With an incredible smooth delivery and big frame he has an easy time filling the zone. He possesses a very nice changeup and high very fastball which complements his breaking stuff very well.
Looking forward to seeing how he progresses going into his freshman year at this year.
