Notes

Comments

2/18/24

RHP Jack Gianikos (Maine South, 2026) stands out immediately thanks to his long-levered, highly-projectable, 6-foot-3, 180-pound, loose-bodied frame. The arm plays loose and quick from a ¾ slot and the fastball seemed to play harder than the velo indicated (83-84.2 mph). He currently throws a curveball and a slider with the slider showing better feel and action on this day at 68-70.8 mph; plays with sweeping 10/4 shape and peaked at 2,394 rpm. His changeup was also a quality offering playing at the bottom of the zone with sink and run. Could easily see the velocity jump at any time for the upside 2026 arm.

2/18/24

Positional Profile: RHP/1B
Body: 6-3, 180-pounds. Highly-projectable, long, high-waisted frame. Delivery: Compact, clean, tall and fall delivery, works on-line and on balance.
Arm Action: RH. Short arm action, 3/4 slot, plays loose and quick out front.
FB: T84, 83-84 mph. Clean and easy out of the hand, late running action at times. Played around the zone. T2067, 1942 average rpm.
CB: 65-67 mph. More 11/5 shape than slider, distinct action. T2185, 2114 average rpm
SL: 68-71 mph. Plays with arm speed and intent. Tight spin, late sharp action and feel. T2394, 2161 average rpm.
CH: 73-74 mph. Quality offering, kills spin, late sink and run at the bottom of the zone. T1129, 923 average rpm.

10/15/23

At 6-foot-3, 180-pounds RHP Jack Gianikos (Maine South, 2026) is another arm to know from this event. Gianikos’ fastball had some life out of the hand (T18.3” VB) sitting at 82-84 mph and he threw it for strikes (80%), too. (84.3 mph max), finding the strike zone 80% of the time. Gianikos showed two different breaking balls; a curveball at 65-69 mph that spun off an 11/5 plane, and a 69-70 mph slider with heavy horizontal action (19.8” HM). To round out his four-pitch mix, Gianikos threw a 74-78 mph changeup that flashed fade from a slightly lower arm window than his fastball.

10/15/23

Positional Profile: RHP/1B
Body: 6-3, 180-pounds. High-waisted with developing strength.
Delivery: Simple delivery, gets into backside at balance, medium leg lift, tall/fall delivery, lands square at footstrike.
Arm Action: RH. Clean arm action, 3/4 slot.
FB: T84, 83-84 mph. Has life out of the hand. Plays up in the zone with some ride. T2160, 2063 average rpm.
CB: 65-69 mph. High spin, 11/5 shape, keeps low in the zone. Out-pitch potential. T2402, 2268 average rpm.
SL: 68-69 mph. 10/4 action with some depth. Throws for strikes. T2332, 2299 average rpm.
CH: 74-78 mph. Arm-side fade. Plays low in the zone. T1623, 1454 average rpm.

2/22/23

RHP Jack Gianikos (Maine South) was arguably the most projectable 2026 arm in attendance. Gianikos sports a long, loose-limbed. 6-foot-2, 165-pound and loose, quick arm. He showed control of all three of his offerings, led by his low-80s fastball that plays clean and lively out of the hand with much more to come down the road. The curveball and slider have similar traits with above-average feel for both; his curveball showed late sweeping action, averaging 2140 rpm, 15.7 average inches of horizontal movement and has a chance to be an out-pitch moving forward.

2/18/23

Positional Profile: RHP/1B
Body: 6-2, 165-pounds. Proportional frame with room for growth.
Delivery: Fluid delivery, stays closed at balance point, aggressive at foot strike.
Arm Action: RH. Loose, quick arm 3/4 slot.
FB: T83, 81-82 mph. Lively pitch, gets late arm-side life at times. T2209, 2108 average rpm.
CB: 66-68 mph. Above-average feel, thrown with intent, late sweeping action, potential go-to offering. T2199, 2140 average rpm.
SL: 66-68 mph. Similar action and velocity to curveball. Lands for strikes consistently. T2154, 2097 average rpm. 

8/21/22

Positional Profile: RHP/1B
Body: 6-1, 145-pounds. High-waisted frame with room to fill out.
Delivery: High athletic leg-lift into balance point, drop/drive lower-half, stays on back-knee throughout stride, remains in-line to the plate.
Arm Action: RH. Short arm out of the glove into a high 3/4 slot.
FB: T75.9, 74-76 mph. Running action to the arm-side. T1989, 1913 average rpm.
CB: 61-65 mph. Flashed sharp 11/5 shape with depth. T2087, 2022 average rpm.
SL: 62-64 mph. Shorter 10/4 shape. T2066, 2006 average rpm.
