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 third base position.
Previous Top Three:
1. Xavier Neyens
Yes.. I know he is a shortstop right now. But even with that, he is still the top third base prospect too if he had to make a move. Neyens was selected by the Astros in the first round of the 2025 MLB Draft and signed for $4.12 million, the organization’s largest bonus since Alex Bregman received $5.9 million in 2015. A left-handed hitter out of Mount Vernon High School in Washington, Neyens boasts some of the most impressive raw power in the 2025 draft class. While he has a strong arm suited for a corner infield or outfield spot, it’s his powerful bat and advanced hitting ability that made him a top pick. Standing 6’4″ and weighing 210 pounds, Neyens projects as a formidable middle-of-the-order presence. He’s the first high school position played selected by the Astros in the first round since Tucker in 2015.
2. Caden Powell
Powell was selected by the Astros in the 6th round of the 2024 draft and signed overslot for $422,500. The 21-year-old is listed at 6’3″ and 200 lbs with room to grow. He started his college career at Oklahoma but transferred to Seminole State College where he was named the D-1 junior college player of the year after hitting .502 with 32 HR, 104 RBI and a slugging percentage over 1.000. Powell started of the year great in Single-A posting an OPS over .800 while showing off power and speed. He missed some time with an injury and had some struggles when coming back, but his power and upside with the bat is legit.
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.
