Notes

Comments

10/19/25
It was a strong bullpen session from Necessary who showcased a strong four-pitch mix, throwing from a deceptive high 3/4 arm slot that added life and angle to his arsenal. His FB (4-seam and 2-seam) sat 78-80 mph with consistent arm-side run and sink, locating effectively to his arm side with a top spin rate at 2014 rpm. The SL worked 65-68 mph with 2500+ spin, showing tight, late break and the ability to bury it down and in the zone as a potential put-away pitch in two-strike counts. His CB sat 64-65 mph with spin peaking at 2576 rpm, one of the event’s best, showing depth and shape, while the CH (74-76 mph) displayed late fade and drop with spin rates between 1487–1530 rpm, rounding out a polished mix.
