The Boston Red Sox have no problems with their first base depth. After acquiring Willson Contreras in a trade with the St. Louis Cardinals this past offseason, it seemed like the organization had lost trust in its homegrown player.
After suffering a torn rib cartilage in 2024 and a torn left patellar tendon last year in 2025, Triston Casas was due for a big year in 2026. He was supposed to catch up in Fort Myers and start rehab soon, but he's suffering a setback due to rib soreness. While obviously troubling for Casas, this is the perfect opportunity for a 6'6", 270 lbs, 19-year-old top-five prospect in the system to shine.
Justin Gonzales, who recently gained 60 lbs over the last year in the pros, just turned 19 this past New Year's Eve, so he's technically entering his 19-year-old season right now. Ironically, he's the last power-hitting prospect to come through the system since his counterpart, Casas. Originally listed as an outfielder with a great arm, he'll most likely be at first base when he comes up to the Red Sox in 2028, given the huge weight gain. However, he's very agile for his size and can move very well.
Justin Gonzales's Time Could in Boston Could Come Sooner Than Later
Something else may happen in 2028, it's regarding Contreras. He has a $20 million club option for that season, which the Red Sox will most likely cut loose on. That will make room for Gonzales to swoop in and take that full-time first base spot. If you think about it, given Contreras's contract and Casas phasing himself out due to injury issues, patterns are leading to this exact outcome. Many believe that the Red Sox should not trade him by any means, and they might get their wish.
This is a huge opportunity for Gonzales, as he'll be starting in a stacked High-A Greenville team this year, alongside top 15 prospect infielders Henry Godbout and Yoelin Cespedes, outfielders Yophery Rodriguez, Isaiah Jackson, and catcher Adonys Guzman. That's not even getting into that loaded rotation with four of them as their top 10 prospect pitchers: Juan Valera, Kyson Witherspoon, Anthony Eyanson, and Marcus Phillips.
Back to Casas, his setback is specifically an intercostal strain, which happens to the muscles around the area of a recently fractured rib or torn cartilage. In short, his torn cartilage is nagging on him again, and those injuries can easily be re-injured. Depending on the pain level, recovery time can take about eight weeks.
With updates on that setback looming near, the opportunity for Gonzales is essential. He can easily rise through the system like Payton Tolle did if he makes adjustments to his strides and aggressiveness at the plate, along with lifting the ball more. If he finds consistency, everybody takes cover, because baseballs will be hit like they were shot out of a cannon.
For someone like Gonzales, who hit a 117 mph single in spring training that seemingly looked easy for him, that's not going to be hard for him to do whatsoever. Expect a monstrous breakout season for him this year.
