Red Sox promote monster No. 2 prospect Justin Gonzales to Double-A following another big game

The Boston Red Sox have promoted first baseman/outfielder Justin Gonzales to Double-A, according to Mike Rodriguez.

Gonzales finished off his High-A career hot, going 3-for-4 with two home runs. He continues to be one of the most electric prospects in the system and is currently ranked second in the Red Sox organization behind Franklin Arias. Gonzales now finds himself on an exciting Portland Sea Dogs’ roster in Double-A, and just a few steps away from the majors.

Gonzales entered the 2026 season as one of the most intriguing prospects in baseball. It's believed it's larger than his listed height and weight of 6’5”, 210 pounds. He possessed elite power potential, but needed to elevate the baseball more. In 2025, he hit only four home runs in 410 at-bats across the FCL, Single-A, and High-A.

If he could elevate the ball, could he continue to draw walks while limiting strikeouts? We got an answer to that question in 2026. Gonzales started elevating the ball this season, which has led to more home runs. Meanwhile, the strikeout rate has seen only a minimal rise, and the walk rate has actually jumped up nicely.

In 89 games in High-A this season, Gonzales slashed .271/.391/.463 with 12 doubles, two triples, and 17 home runs. He drove in 58 runs, scored 68, and stole 11 bases. The right-handed hitter only struck out 18.7% of the time and walked an impressive 13.3% of the time.

Last season, Gonzales hit the ball on the ground 57.4% of the time. He hit line drives 21% of the time and fly balls 21.6% of the time. Those are depressing numbers for someone with absurd light-tower-power.

Those numbers look dramatically different this year. His ground ball rate is down to 46.6%, while his line drive rate is at 23.7% and his fly ball rate is up to 29.7%.

The other issue some will point to with Gonzales is maturity. He didn’t run out a dropped line drive earlier this season, then didn’t play the next few games. Of course, he’s also known for his very long home run trots and was famously involved in a brawl this season, which led to him being suspended.

However, fans shouldn't be worried. Gonzales has effortless swag on the field. He’s a 19-year-old who is having fun. Okay, he didn’t run out a line drive that was dropped while he was in the midst of a slump. He was frustrated; every player has done that at some point. Arias was also disciplined earlier this year, and that’s worked out fine. Young players sometimes need to be sat down and taught.

Watching him play, I never see Gonzales not hustle in the field. He’s been moving around the bases on home runs much faster since the brawl. It feels like someone might have had a few words with him about it, and he’s realized how important he is to his team winning and decided to keep the slow trots to big moments (like walk-off home runs).

It seems like he understands he’s playing a game and wants to have fun. He walks with a limp and wants you to know that there’s a very real possibility he could hit a ball 500 feet and moonwalk around the bases. What are you going to do, step to a giant?

Gonzales's play could go many ways after his Double-A debut. Will the power continue to develop? Can he keep hitting the ball in the air? Will he continue to draw walks and limit strikeouts? Is he going to be a first baseman or can he stick in the outfield with that incredible arm? The Red Sox likely didn’t want to trade him because you don’t want to be the team that traded away what he can be. Sure, he could fizzle out like anyone else, but few prospects possess the ceiling of Gonzales.

Look at the mountain of a man and watch him hit a baseball and tell me you can’t envision a couple of 40 home run seasons. I’m not saying it’s definitely happening; that’s an absurd label to put on someone. But, really, you can’t even picture it?

In the most Gonzales way possible, he hit two home runs in his final game in High-A. The final clip of Gonzales at the level is in a Black Spinners jersey (the best variation of the Greenville Drive uniforms and potentially the best unis in the system), turning his hat backwards after receiving the final out at first base, untucking his jersey, and walking with a limp like he knows he’s on to bigger and better things.

Expect to hear a lot of barking in Portland. The Big Dog is officially in Double-A. Woof woof.
