Boston Red Sox Top Prospects: No. 7 Justin Gonzales

Saying that Justin Gonzales is a physical specimen is an understatement. Entering spring training this season, Gonzales was measured at 6-foot-6 and 277 pounds. That was after being last measured at 6-foot-4 and 210 pounds. While the previous weight may have been outdated, it’s still fascinating to see the 19-year-old continue to grow, even stating that his goal is “to be like Aaron Judge."

Gonzales was part of the team’s 2024 international free agent class and in his first professional season at the Dominican Summer League, he put on a show offensively by hitting .320/.391/.517 with four doubles, five triples, five home runs and 29 RBIs in 47 games. He would come stateside for 2025, when after just one game in the Florida Complex League, he would be promoted to Low-A Salem and play in 81 games. He went on to hit .298/.381/.423 with 23 doubles, two triples, four home runs and 27 RBIs in that stretch before finishing the season with 11 games in Greenville.

Offensively, there is no doubt that Gonzales is one of the organization’s best prospects. He has a quick bat and has solid barrel control for his size. His 90th percentile exit velocity was 107 mph and his highest was 113 mph. Thanks to an advanced approach at the plate, he’s able to let a pitch come in to him deep and send it the other way to right field instead of just trying to pull everything. With a good understanding of the strike zone, he doesn’t strike out too much, though he does struggle to recognize secondary pitches. Despite being just 19 years old, he's already impressing in spring training. On March 2, he was called up to play in a Red Sox spring training game and had a single with an exit velocity of 117.3 mph. It would have been the 12th-hardest exit velocity in Major League Baseball in 2025. 

His power is really impressive as it’s viewed as being easily above average by scouts. With his size and swing, he generates easy pop as the baseball jumps off his bat and he can drive the ball to all parts of the field. Unfortunately, he doesn’t take full advantage of it due to a 57% groundball rate. If Gonzales can improve his bat path and launch angle, he could really tap into his power and become an offensive beast.

Defensively, Gonzales has spent time at first base and all three outfield positions. In 2025, he spent the entire season split between the three outfield positions, though due to his size he will likely play either first base or a corner outfield position as he continues to advance through the minor leagues. He showcased good range in the outfield but struggled when it came to his jumps and routes. Despite that, his arm is considered above average and would play well at either corner outfield position.

Gonzales’ speed is also below average, though he moves well for someone his size. While he won’t steal many bags, he won’t clog up the basepaths and should be able to go from first to third or second to home on outfield hits.

Gonzales will look to continue his impressive start to his professional career in 2026. He’ll be entering his first full season (having only played 93 games in 2025) and it’ll be a good chance to see how he holds up across a full stateside campaign. Should Gonzales continue to develop at the plate, there’s a chance he could be up with Boston by 2028. Unfortunately, with an All-Star ceiling comes a low floor, making him one of the bigger boom-or-bust prospects in the system.

Gonzales will open the season with High-A Greenville after appearing in just 11 games there last season. The Red Sox have been aggressive the past few seasons with promoting their top players, and should Gonzales avoid any prolonged struggles, he should be able to make it to Double-A Portland before the end of 2026.
