Standouts from the 2022 High School All-American Game

July 16th, 2022

LOS ANGELES -- Scouts consider Aidan Miller one of the top hitters and overall top prospects in the 2023 high school class. He lived up to that reputation Friday afternoon at the Major League Baseball-USA Baseball High School All-American Game at Dodger Stadium.

In the most star-studded prep showcase event of the summer, Miller went 4-for-5 and drove in three runs to lead his American League squad to an 13-8 victory. The J.W. Mitchell HS (Trinity, Fla.) infielder won the MLB Develops MVP Award presented by Chevrolet, which includes tickets to Game 2 of the 2022 World Series.

"Just being out here with the best players, best coaches in the country, it's awesome," Miller said. "I think I was a little more aggressive in my last three, four at-bats. I got into some good counts, got some good barrels."

After grounding out in his first at-bat, Miller knocked in runs with singles in the third, fourth and sixth innings, and singled again in the eighth. His third-inning knock gave the AL a lead it wouldn't relinquish and was the second-hardest hit ball of the day with an exit velocity of 100 mph.

A potential Top 10 pick next year, Miller is a 6-foot-2, 210-pound infielder who profiles best as a third baseman. He's the younger brother of Reds 2020 Competitive Balance Round B pick Jackson Miller, and an Arkansas recruit.

Other standouts in the game included:

Garrett Baumann, RHP, Hagerty HS (Oviedo, Fla.): In a game that featured 21 runs, 30 hits, 17 walks and seven errors, Baumann was the most efficient pitcher. He needed just 13 pitches to navigate a perfect fourth inning, working with a 91-94 mph sinker and showing confidence in his low-80s changeup. He used his 6-foot-8 frame to create quality extension as well.

A.J. Ewing, INF, Springboro (Ohio) HS: Ewing reached base in all six of his plate appearances, working five walks and hitting an opposite-field single.

Gavin Grahovac, OF, Villa Park (Calif.) HS: One of the most powerful hitters in the 2023 class, Grahovac stayed back on a fourth-inning curveball and pulled it to left field for an RBI double with an exit velocity of 98 mph. He also showed nice hustle in his first at-bat, beating out a ball that he grounded off Madison HS (Vienna, Va.) right-hander Bryce Eldridge.

Braden Holcomb, INF, Foundation Academy (Winter Garden, Fla.): The 6-foot-4, 220-pound slugger was the only player to homer with wood bats in batting practice, going deep three times. He produced the hardest-hit ball during the game, smoking a 92 mph fastball for a double at 104 mph. He also drew a pair of walks.

Zander Mueth, RHP, Belleville (Ill.) East HS: Mueth showed three pitches in a scoreless sixth inning. He notched his lone strikeout with a 94 mph fastball and topped out at 95, spun some tight low-80s sliders and elicited a swing-and-miss with his mid-80s changeup. The projectable 6-foot-6, 195-pounder matched Baumann with the highest peak extension of the game at seven feet, four inches.

Zion Rose, C, Brother Rice HS (Chicago): A better athlete than most catchers, Rose showed off some quickness on a pair of extra-base hits -- a triple stroked at 98 mph in the third inning and a double in the ninth. He also had the wheels and aggressiveness to score from second base on a grounder that barely left the infield.
