4/1/17 Game Notes: Ball State Commit. Fast twitch, electric RHP at 6 ft, 165 pounds. Athletic arm that was quick and loose. Worked with great tempo and rhythm throughout. Sat 90-91 first inning touching a 92 with little arm side sink. Settled into the game at 88-90. Threw both breaking balls for strikes - curve ball was 11/5 sharp at 75mph and slider was 78-79mph. Commanded fastball to both sides of the plate. Threw FB above the hands for strikeouts. Finished with a complete game no hitter striking out 10 LN hitters. Great competitor on the mound.
Feb 2017 Super 60: 
Ball State recruit. 6-foot, 165-pound right-handed pitcher, wiry-thin build, narrow shoulders, overall quick-twitch athlete. Quick, loose, athletic arm, high-3/4 slot; rhythm and tempo in delivery. Worked fastball at 88-89 mph, mostly straight. Throws two breaking balls: curveball ranged between 78-79, slurvy shape; slider ranged between 80-81 with some sharpness. Also threw a 78-80 mph changeup, excellent feel for pitch, thrown for consistent strikes with arm-side sink. Overall high-level athlete, ran a 6.52 60 at a previous PBR event.

The 6-foot, 160 pound right-hander possesses quick arm speed from a loose, high 3/4 arm action.  Fastball has life at 87-90, touching 92 on multiple occasions.  Slider is thrown at 77-81 with sharp action; throws for a strike in any count.

5/10/16 GAME NOTES: 
6-foot, 160 pound Ball State commit and leadoff hitter went 2-3 with a pair of doubles in a 4-1 victory over Shenandoah Tuesday evening. Rangy outfielder uses plus speed to cover gaps and get around the bases. Very strong outfield arm. Sets up athletic and slightly open at the plate. Uses a small toe tap and average bat speed to produce line drives.  

6-foot, 160 pounder ran a 6.68-60 and was 92 from the OF from a loose, high ¾ arm action.  Good life on his throws.  Athletic actions in the field with quick feet.  At the plate shows quick twitch with quick hands.  Average use of the lower half, tendency to dive.  Fair approach.  Line drive hitter.  Recorded a high exit velocity of 85 mph. PITCHING 6-foot, 160 pounder pitches from a high ¾ slot with quick arm speed.  Loose arm action.  Regular effort in the delivery with smooth rhythm.  Uphill shoulders, stays in line.  Fastball was an easy 85-87 with run.  Threw a curveball at 74-78 and a slider at 77-79.  11/5 action with sharp break on the curveball.  Changeup has good sink with occasional run at 77-79.   

  Wiry 5-foot-11, 155-pounds but showed as big of an arm as any. It’s a short quick, lively arm action that worked 86-89 with the fastball and showed an equally impressive curveball. It too is a swing and miss curveball at 77-78 that seemed to disappear on hitters.

5/3/19: Undersized, electric-armed righty at 5-foot-11, 165 pounds Jameson has clean arm action and a super-quick arm. Showed a high effort delivery with rush and recoil; his lower half is in need of some cleanup. During this Week 12 start he looked a bit fatigued from the beginning as his slight build and a heavy workload may be catching up to him. However, he managed to throw 131 pitches in this 8-inning outing and struck out 16. For the season Jameson has 120 punchouts in 73.2 IP. On this look, he ran his fastball up to 97 mph, while pitching at 93-95. The heater lacked much life and was hit hard, especially during the early innings. Slider was average to above average at 81-85 mph, but played less early in the game due to the lack of command. As the game progressed he found feel for the pitch, throwing it often for swing/miss. Changeup looked similar to a soft two-seam fastball at 88-89 mph. Dropped his hand a couple times to take more off the pitch at 86-87. Jameson had a reliever look this outing, yet earlier in the season he was regarded as a potential MLB starter with three above average to plus offerings and solid control. Looking to the future, he's athletic and should be able to make the needed adjustments to hold together his delivery for 100 pitches each outing. With maturity and strength gains he could develop the durability needed to post every fifth day as a starter in pro ball. If not, his three-pitch arsenal and premium velocity profile well to the back of a MLB bullpen. Depending upon which day a cross-checker or Scouting Director saw Jameson, he could go anywhere from the 2nd round to early in the 4th. (Seifert)
