Notes

Comments

2/17/24
Uncommitted. Highly projectable 6-4 190lb frame and adding strength. Fast arm and creates quality extension down the hill with his mobile lower half. Mid-depth AA with a H3Q slot. Somewhat erratic with command but very tough to square up when in the zone. FB velo was 87-88 and reached 90 in the first inning but drifted at times and predominately sat 84-87 with good underlying metrics (above 20” IVB). Still developing secondary offerings but showed some ability to tunnel his offspeed pitches and as they are refined will play very well off his FB. CB (73-76) showed some sharp, late movement that will generate s/m when located well and flashed a CH at 74. Raw with lots of upside.

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.
