Verbally committed to Michigan.


Uncommitted, 6-foot-2, 145-pound, long-limbed, high-waisted, right-handed pitcher with plenty of room for continued physical development. Started on the mound and impressed in his four innings of work. Did not allow a hit or a run while striking out eight and walking one. Even-keeled, low-pulse demeanor on the mound, seems to be in total control on the mound and attacks with a plan. Methodical, controlled delivery, high-front side, hides the baseball on the back-side, highly-repeatable. Clean, uninterrupted arm action, high ¾ slot. Utilized a fastball/breaking ball throughout. Fastball comes out of the hand clean and easy, late arm-side-run, located down in the zone and repeated quality strikes to the glove side; sat anywhere from 82-86 mph throughout. Pitches with low effort at 82-84 and had 86 in his back pocket whenever he wanted. Looked to be manipulating his breaking ball early on in the outing but as the start went on, it was evident he was mixing in a curveball and a slider. Both breaking balls tunnel well off the fastball. Curveball has 11/5 shape, feel for the zone, occasional bite, 70-73 mph. Slider, 74-75 mph, has a shorter, more horizontal 10/4 shape; ability to show in the zone and end up out of the zone with two strikes; quality go-to two strikeout/swing-and-miss offering. High-follow polished 2023 arm on the rise.

The 14U Top Tier Americans started off the day with an excellent pitching performance, turned in by Benjamin Oosterbaan. The long and lanky right-hander was dominant on the day, tossing a complete game shutout while only allowing three hits and striking out eight batters. Oosterbaan had control of all three of his pitches, throwing 53 of his 80 pitches on the day for strikes. His fastball generated consistent soft contact while topping out at 78 mph and sitting between, 75-77 mph. Oosterbaan’s curveball sat between 68-70 mph with a 10/4 shape, while his changeup was thrown near fastball arm speed and ranged between 67-70 mph. His ability to locate his fastball, and throw his offspeed for strikes, kept opposing hitters off balance, leading to Oosterbaan’s dominant performance on the mound.
