Jayden Kieler, Leo JR/SR Highschool (IN), 2027
Positional Profile: RHP/1B
Body: 6-3, 205-pounds. Athletic, projectable build on a large, developed frame.
Delivery: Stretch primary delivery w/ a relatively tall, compact leg lift and low balance point. Shoulders work even down the slope with lots of separation. Big stride down the slope achieving both extension and abv/avg hip separation in delivery.
Arm Action: RH. Loose, whippy arm action from an over the top slot.
FB: T79, 74-78 mph. Profiles as a Cut FB. T1970, 1847 average rpm.
SL: 61-65 mph. Gradual gloveside movement. T2035, 1978 average rpm.
ATH: 7.71 runner in the 60.
Jayden Kieler, Leo JR/SR Highschool (IN), 2027
Positional Profile: RHP/1B
Body: 6-3, 205-pounds. Athletic, projectable build on a large, developed frame.
Hit: RHH. Wide setup with weight prematurely shifted back onto drive leg. Minimal to no load due to weight shift followed by a short, quick hover stride. hands work slightly back and down in time with stride. Head stays steady on the ball. Some bat speed with a line-drive approach on an even plane. 67.7 mph bat speed with 9 G's of rotational acceleration.
Power: 90 max exit velocity, averaged 81.4 mph. 306' max distance.
Arm: RH. INF-76 mph. Loose arm action from a 3/4 to s sub 3/4 arm slot. Lots of shoulder separation in throwing mechanics.
Defense: Fundamental footwork off the bag at 1st. Sure hands with an easy exchange.
ATH: 7.71 runner in the 60.
I like the upside that '27 RHP Jayden Kieler (Leo) showed during his bullpen session. A big-bodied, 6-foot-3, 205 pounder that will mature into more strength to improve his overall body composition - Kieler was up to 82 mph on the fastball with plenty left in the tank. The arm works clean with a more compact circle to a 3/4 release point, and he was able to get in the zone with all three of his offerings. Kieler showed a slurvey breaking ball at 72-74 mph, but I liked his fading, 75-77 mph changeup as his best off-speed pitch. The front leg swings open at landing causing a bit of inconsistency, however this is a small mechanical adjustment that is easily fixable and should clean up his overall command and improve his velocity. Kieler shows shades of a younger Jack Grunkemeyer, a current SR signed to Northwestern University, and established himself as a '27 follow after his performance this weekend.
