As we inch closer to the 2026 season, I am going to give top three prospects at each position. This will be based on where they currently play and also where they may end up. This will culminate with my newly updated top 30 prospects before the season starts. This week, we are looking at the second base position.
Previous Top Three:
1. Brice Matthews
Matthews entered the 2023 draft as one of the most athletic prospects in the Big Ten. The 21-year-old broke out during his junior season at Nebraska, slashing .359/.481/.723 with 20 home runs and 20 stolen bases. Known for his quick swing and impressive exit velocities, Matthews projects for 20–25 home run power, with strong pull-side pop. While he’s seen time across the infield, the Astros appear committed to developing him at second base. There is some swing-and-miss in his game, but those concerns are lessened due to his potential. Matthews backed up the scouting reports in 2025, hitting .283 with 10 home runs and 25 stolen bases over 73 games at Triple-A, earning a call-up to Houston.
2. Nick Monistere
Monistere was selected by the Astros in the fourth round of the 2025 MLB Draft out of Southern Mississippi. He broke out during his junior season, batting .323 and leading the Sun Belt Conference with 21 home runs over 63 games. Primarily a second baseman in college, Monistere brings defensive versatility, with the ability to handle multiple positions around the field. He also offers legitimate power at the plate, making him an intriguing offensive prospect with impact potential. He had some struggles following the draft but it was limited experience in Fayetteville.
3. Alejandro Nunez
Nunez signed with the Astros back in 2022 for $10,000 and has made his way through a few levels. He is a lefty hitting infielder and while he doesn’t have a big standout tool, he does a little bit over everything. He has some pop, steals some bases, limits strikeouts and plays multiple positions on the field. This season in High-A the infielder hit .269 with 19 doubles, 8 home runs and 22 stolen bases over 94 games. He should be in Double-A in 2026, which will be a big chance for him to have a breakout season. He is only 21 years old.
