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

#uncomitted ‘26 OF Alex Ott (@MountSiBaseball) helped the Wildcats answer back immediately in the first

The lefty laced a middle-in fastball over the CF’s head, showing off the wheels for a 3-run, inside the park HR

Ott reached base in all three of his plate appearances, finishing 2-2 with a walk and 4 RBI

#uncommitted ‘27 OF Austin Catini (@MountSiBaseball) had a nice night at the plate, including this RBI single

Heavier barrel through the zone with triple digit exit velocity pop posted in a showcase look last summer. Quality runner that can stick in all 3 OF spots. Finished 2-2 with 2 singles and a walk in this look
