August 26, 2026
Dylan Grenz
Assistant Scouting Director

As we conclude the summer showcase circuit, Prep Baseball Washington continues with our latest series of player rankings updates. Whether at open ID's or invite-only events, many players across the state have solidified their prospect status with showcase performances throughout the summer. With these looks in mind, today we unveil our update for the class of 2028.

Washington's 2028 class stands out as an immensely talented and deep group, with 145 players comprising the latest list. Many players saw changes in their ranks after performances at events, including Scout Days, Summer ID's, and our biggest event of the summer, the invite-only Pacific Northwest State Games. A majority of the top prospects were also seen at LakePoint at the coveted Prep Baseball Future Games. To view the full rankings list, click here.

Below are notes on the latest rankings list, including notes at the top, Future Games standouts, and other big summer winners.

At The Top

A new number one player tops the 2028 list for Washington in Battle Ground's Collin McGowan. Seen at NPI and at Future Games this summer, the standout two-way talent excelled at every opportunity and carries an immense ceiling moving forward. A towering 6'5 athlete, McGowan features easy low 90's velocity on the hill and triple digit exit velocity power with a strong approach at the plate. Prep Baseball's VP/Scouting Shooter Hunt held high praise for McGowan after his performance in Georgia, with his takeaways below.

"McGowan possesses an unteachable frame at 6-foot-5, 225-pounds, and comfortably pumped in fastballs at 90-93+ (2500+ rpm) with some ride and run in an outing that came at the end of a long day as a position player. Comfortable simply tossing fastball after fastball in a quick two-inning look, the slider flashed as an out pitch at 80-82 with shorter action and some depth. He also presented an intriguing changeup in the mid 80s. Powerfully-built with defined strength in the look of a future tight end on the gridiron, McGowan is an exceptional athlete for his size, and his short, quick arm is indicative of his position player status (which is also quite intriguing). While he is likely (and should!) continue to hotly pursue his power-hitting third baseman status, this look on the mound continued to exhibit the look of a future frontline arm."

Ranked within the top 50 of Prep Baseball's national rankings for the 2028 class, McGowan has thoroughly established himself as a must-follow name for coaches nation wide.

Kentlake INF Lincoln Moore holds the number two position in the rankings after a strong summer in his own right. Fresh off of a 3A state championship this spring, Moore's pristine 6'2 frame continues to show plus defensive ability at shortstop. A 6.72 runner with throws up to 88 MPH across the dirt, Moore's glove played in-game with an excellent blend of range and fluidity. At the plate, Moore has blasted exit velocities up to 106 MPH in previous looks and works to all fields with a mature approach. Seen at Future Games and PNW Scout Games this summer, Moore's best swing came late in Georgia with a towering solo home run to left field. Moore has a real chance to be the best position player to come out of the PNW in the last couple of years with an exceptionally well-rounded skillset.

A massive summer riser and one of two new additions to the top ten, Kingston HS RHP Vaka Tameilau jets all the way up to the number three spot in the rankings after a breakout couple of outings. The lean-framed righty displayed a major jump in "stuff" on the mound from a look this winter to a look at NPI early in the summer. Returning to LakePoint late in July at Future Games, he only improved his stock further. Shooter Hunt writes further about Tameilau's look at Future Games as one of Hunt's 75 Impact Arms at the event below.

"Long and lean at 6-foot-3, 160-pounds with a staggering amount of physical development to come, Tameilau turned in an electric look on the final day of the Future Games. Quick-armed with an efficient, short path, the fastball worked 91-93+ before countering with a plus-changeup at 83-85 with a power-look that included late diving action. He also displayed a firmer, bullet slider in the mid 80s. Driving firmer off the back side, his quality movement patterns combined with a projectable frame promise bigger advancements in the near future."

The true feel for all three pitches, ability to fill the zone and immense projectability give Tameilau as high of a ceiling as any arm moving forward, with hopes of a frontline starter down the line.

Future Games Standouts

Both from a results and pure "stuff" perspective, few arms had as much success at Future Games as Liberty RHP Tate Tuininga. The 6'6 arm works up to the fifth spot in our latest rankings update. Setting the tone as the first arm to throw for Team PNW, Tuininga was exceptional, striking out six across his two innings of work with a high-spin fastball topping out north of 93 MPH. Loose out of the glove with a longer arm stroke, he pounded the zone with intent to both sides while flashing upside to breaking ball in the mid 70s along with a faded changeup at 81-83. If the righthander can consistently fill the strike zone, he has a real chance to be the next in line of a talented crop of arms to come out of the PNW in recent years.

On the position player side, Eastlake OF/1B Ben Byeman opened the eyes of scouts start to finish at LakePoint. A sturdy-strong 6'0, 205 pound prospect, Byeman started well with a 6.79 60 time and quality BP rounds during his workout. In-game, the bat really shined in all three games, finishing the week 3 for 6 with a HR, double, 2 walks, 2 RBI and 3 runs scored. Strong from the ground up with a heavier barrel through the zone, Byeman carries power to the pull side and big part of the field with a repeatable operation from the left side. Moved up to the sixth spot in Washington's 2028 rankings, he's sure to be a coveted player for college recruiters around the country.

Another major breakout bat, Eastmont's Izik Ontiveros carries immense bat speed and raw power. The righthander slugged at every look leading into the summer, mashing balls in BP up to 106 MPH and 398 feet at a winter showcase. At LakePoint, the power was on full display in-game, with every one of his four hits going for extra bases. The pull power and shorter levers yielded a ton of hard contact to left field with a home run and 3 doubles, with 6 RBI and 3 runs scored as well. The defense carries rawness but is developing at catcher, with a potential move to a corner possible down the line. Onitveros rises up to the 12th spot in the rankings behind an incredibly deep and skilled top ten.

Other Winners of the Summer

A quality performer at PNW State Games, West Seattle LHP/OF Brady Stenberg rises up in our latest update. In his first Prep Baseball showcase appearance, Stenberg had a tough matchup when he was on the mound against the ProCase Team. The lefty more than held his own and impressed in a big way, working through two quick scoreless innings before running into a bit of trouble in his last frame. Nonetheless, the skill on the mound was apparent, filling the zone with a FB 83-87 MPH. The CH at 78-80 MPH had some late fade, while the SL at 72-74 MPH held over 2330 RPM on average with sweepier action. Stenberg also carries real juice at the dish with EV's up to 98.8 MPH and balls hit up to 386 feet. Stenberg carried over from what was a strong showing during the HS season and should be a dominant two-way force as he enters his upperclass years.

Seen at the Spokane Summer ID, Kamiakin's Stener Kvinsland flashed immense arm talent and shoots up over 50 spots in the rankings. The arm talent stood out in INF/OF looks this spring and exceeded expectations in Spokane with throws up to 95 MPH from the outfield, the best number posted this year at a Prep Baseball Washington showcase. The arm talent translated to the mound with a fastball 88-89 T89.6 MPH. Kvinsland works through a steady-paced wind with a continuous arm swing and late intent into a 3/4 slot release. The electric heater was paired with a CH at 75-79 MPH and a CB at 68-70 MPH. The bat trails the arm a bit to this point, but did drive balls up to 95.4 MPH in BP rounds. 

Few bats in the 2028 class delivered a more eye-opening offensive performance at PNW State Games than the Inglemoor's Titan Fraser. Fraser gets to his power with a nice combination of barrel accuracy as well, showcased with EV's up to 103.4 MPH while averaging 94.9 MPH in his BP rounds. The bat stays through the zone well with a strong lower half, working the gaps in-game as well with a pair of XBH's. Fraser flashed at times defensively with developing arm strength and some lateral agility. Fraser continued what has been an impressive 2026 in Ridgefield and rises up the rankings yet again in this update.
