Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Vizual Edge: 77.04 Edge Score
Uncommitted. 6-foot-3, 190 pounds. This was one of the most exciting finds of week 10. With a prototype frame and plenty of athleticism in the delivery, it’s a guy you immediately lock in on. What was most interesting about him was not only the insane angle his crossfire delivery creates, but also his ability to throw strikes with it. Underclassmen arms that throw across their body typically don’t control the FB very consistently, but that’s not the case with Martell. He got a handful of whiffs with the FB at the top of the zone, and was able to locate it both arm and glove side. This is a very difficult AB for a LHH, as he had 5 freezes on the 3 LHH I saw him face. It was also encouraging to see Martell’s velocity climb as the outing went on. He started out at 78-81 for a hitter or 2, then climbed to 79-82 INN 2, then followed that up with 80-82 T83 in his last inning. His CB velo will need to increase to keep hitters off his FB, but I think the better fit would be throwing a SL or CUT to match his lower slot. If he can continue to take steps with his secondary stuff, this will be a unique D1 arm.
