1B Jack Roessler (Waterloo, 2024) first popped to our staff at the St. Louis Open, earning an invite to this event as a result. A 6-foot-3, 200-pound athlete, Roessler continued to swing a strong, physical right-handed barrel, hammering balls on repeat to the pull-side from a short, simple swing in BP. His ability to impact the baseball consistently (89.1 mph) and elevate it on average (281 ft.) are impressive, and his inherent strength flashed at peak, too; 99.6 mph max exit velocity, 336 foot peak distance.
Positional Profile: RHP/1B
Body: 6-3, 200-pounds.
Hit: RHH. Upright setup, toe-tap trigger. Quick, controlled swing with intent, easy juice to all fields, on time and fluid.
Power: 100 max exit velocity, averaged 89.1 mph. 336’ max distance.
Arm: RH. INF - 73 mph. Short arm circle, low 3/4 slot.
Defense: Soft hands, fields ball to body, clean transfer.
Run: 6.80 runner in the 60.
Positional Profile: RHP
Body: 6-3, 200-pounds.
Delivery: Stretch-only, high leg lift, works downhill.
Arm Action: RH. Long, high 3/4, some arm speed out front.
FB: T81, 78-80 mph. Four-seam, some ride through the zone, plays up in the zone. T2220, 2166 average rpm.
SL: 67-69 mph. 10/4 shape, hard bite, out-pitch characteristics. T2167, 2114 average rpm.
CH: 72-74 mph. Circle-change, similar profile to the fastball, developing pitch. T2035, 1926 average rpm.
Positional Profile: 1B/RHP
Body: 6-3, 200-pounds.
Hit: RHH. Tall setup, small leg lift, toe-tap stride. Uphill path, direct to the ball, quick, consistent line drive contact. 76.4 mph bat speed with 18 G’s of rotational acceleration.
Power: 101 max exit velocity, averaged 91.2 mph. 353’ max distance.
Arm: RH. INF - 72 mph. Short, 3/4 slot.
Defense: Two-hand gather, soft hands.
Run: 7.18 runner in the 60.
At 6-foot-3, 200-pounds, 1B Jack Roessler (Waterloo, 2024; IL) doesn’t lack physicality in stature and showed that at the plate throughout his round of BP. Roessler blistered multiple baseballs from a short, uphill right-handed swing, launching four of his batted balls at 320+ feet, including three that traveled more than 345 feet, per TrackMan. His furthest barrel was bashed at 353 feet over the left field wall, leaving his bat at 97 mph, and his 101.2 mph max exit velocity was the second highest of this event. Roessler’s strength aided him in generating easy bat (76.4 mph) and hand speed (24 mph) on average. He’s also a football player and that athleticism shows, as running a 7.18 60-yard dash at his size is impressive. Roessler is a physical right-handed hitter that’s still uncommitted.
Uncommitted. Roessler had a quality week at the plate going 5-for-10 with two home runs, a double, and nine RBIs. In their 10-4 win over Gibault Catholic, he went 2-for-4 with a home run, five RBIs, and a run scored. Against O’Fallon he went 2-for-3 with a home run, two RBIs, and one run scored.
