Last night Mount Si hosted Hazen in a KingCo matchup ‘26 INF/RHP Jimmy Pratapas (@MountSiBaseball/@NevadaBaseball) was a huge contributor all game long, finishing 4-4 with 4 runs scored Durable-strong frame with simple, middle of the field approach. Senior showcased his versatility at the dish, and can also run his fastball up into the low 90’s on the mound as one of the better arms in the state class @JimmyPratapas
