LOS ANGELES, CALIF. - Former Prep Baseball All-American James Tronstein of Harvard Westlake has earned the 2026 Prep Baseball California High School State Player of the Year award. 

Tronstein joins former teammate, Bryce Rainer (2024), as Prep Baseball California State Player of the Year award winners from Harvard Westlake becoming the first winners from the same high school in the eight year history of the award. 

An incredible offensive talent and a Vanderbilt signee, Tronstein had a dominant offensive season after making the move to shortstop full-time after spending the first three years of his high school career in center field for the Wolverines. 

Tronstein slashed .548/.600/1.000 against what has to be considered one of the toughest schedules in the country this season. Despite making a significant swing change, Tronstein was at his best in his final high school campaign en route to earning Mission League Player of the Year and now California State Player of the Year.

A deeper dive beyond the slash line shows Tronstein’s impact on Harvard Westlake’s offense. In 93 at-bats, Tronstein finished with 10 doubles, a triple, ten home runs, 28 RBI, 22 walks, eight strikeouts, five hit-by-pitches, all while scoring 45 runs from the leadoff spot. He also had 15 stolen bases on 17 attempts. 

From the preseason through to the postseason, all Tronstein did was hit. Our first look came during MLK weekend where he smashed against eventual Division I champion St. John Bosco. It was a look at the revamped setup in his swing that saw him drop his hands and hold the barrel more upright. As the numbers show the reworked swing worked to his advantage. 

From 4.7.26…”The appropriately named Tronny Barrels did just that in his first at bat when he ambushed an 88 MPH FB out over the plate and laced a single right back through the middle, nearly taking the pitcher's head off with the shot. While seeing James Tronstein play a baseball game is going to come with a barrel at the plate, this live look gave me a chance to see the totality of his profile. In his second AB, Tronstein got on top of an offspeed offering and hit a grounder to the 5-6 hole, where he showed off the solid above-average run tool in his game to easily beat out the INF single, giving him yet another multiple-hit day in a live look. On the defensive side of the game, this was my third look at Tronstein playing on the INF dirt and second one with him playing SS, where the natural athleticism in his profile shows well. He plays downhill with tempo and confidence to each of the three angles necessary for an SS. He can attack one-handed or two-handed with some feel for catching the ball in the proper spot within the glove. Tronny is comfortable moving laterally and playing in rhythm with two hands when the play dictates, giving him the versatility required of the SS position. The arm strength is naturally there for SS, but there is some polish needed on the arm path/release point to give his throws improved accuracy (which is to be anticipated after a lengthy portion of his early HS career being spent in the OF). There is enough in the foundation defensively for Tronstein that he should get a shot to attempt to stick at SS at the next level, but if there is a move off the spot in his future, he should easily slide over to 2B and be a strong impact level defender at the spot.”

As the season progressed and the numbers continued to consistently improve, Tronstein dazzled in each and every viewing. He shows the ability to do all things necessary offensively, drive the ball to the big part of the field, play small ball and use his speed, and go the other way with power. As the season progressed more-and-more MLB Scouts appeared at Harvard Westlake games. And as they came to find out, there are very few things Tronstein cannot do on a baseball field, and certainly fewer he can do from an offensive standpoint. 

Despite the final game of his high school career ending in a semi-final loss in the CIF-SS to eventual champion St. John Bosco, Tronstein established himself as one of the premier hitters in the 2026 class relative to the MLB Draft in July. With many draft analysts, including those at Prep Baseball, having Tronstein rated amongst the top available players from California, there’s little doubt that Tronstein has earned the honor of being named the 2026 Prep Baseball California California State Player of the Year.
