19-Year-Old First Baseman1B
Boston Red Sox AA
2026 Fantasy Outlook
Gonzales would be a top-50 dynasty prospect if he could consistently lift the ball in the air, but given that he turned 19 this offseason, it's too early to rule out improvements. The 6-foot-4, 210-pound righty hitter can handle first base and is attempting to show he can cover enough ground to play corner outfield. Given that he was 18 all season, Gonzales' 15.9 percent strikeout rate and 9.5 percent walk rate across Single-A and High-A are stellar marks for a player with his plus-plus raw power projection. He had a 113 mph max EV in 2025 and routinely hits rockets to all fields, just rarely of the flyball variety. His 57.4 percent groundball rate and 21.6 percent flyball rate are horrid marks, but that's the one weakness in his offensive game. Gonzales doesn't chase much, but he's an aggressive hitter (50.8 percent swing rate), so he may not log the same caliber on-base percentages of other high-end first base prospects. If Gonzales can cut his groundball rate, he'll rocket up prospect rankings in 2026. Read Past Outlooks

Debuts at Double-A
1BBoston Red Sox  AA
August 19, 2026
Gonzales started in right field, batted leadoff and went 2-for-5 with a run scored for Double-A Portland on Tuesday.
Analysis
The 19-year-old Gonzales appeared in his first game at the Double-A level. He was promoted to the Sea Dogs on Monday after mashing at High-A Greenville, where he posted a .271/.391/.463 slash line with 17 home runs, 12 doubles, 11 steals and 59 RBI over 89 games. He entered the organization as a first baseman and looks like one, but Gonzalez has transitioned to outfield the last two seasons, getting playing time at all three spots.
