The Mercyhurst College alumni was drafted in the 5th round of the 2014 MLB Draft by the Mariners.
Before getting called up from AA Jackson, Altavilla had a sub-2 ERA in 43 games, striking out 65 batters. He saved 16 games as a closer for the Generals.
It was easy to see why he was with the Mariners by the end of the season, and his transition to the big league bullpen went fairly smooth.
He was lockdown pitcher for the Mariners in the last few months of the season, not allowing an earned run in September or October.
