With the 133rd pick of the MLB Draft, the Houston Astros selected third baseman Beau Peterson out of Mill Valley HS (KS).
“One of the top offensive performers on the summer circuit as an underclassman, Peterson has power tools that stick out. He’s 6-foot-3, 210 pounds with a strong, physically-mature build for his age with big raw power. He doesn’t have to sell out his swing to generate that power, staying inside the ball well with a short, lefthanded stroke to use the whole field. He can drive the ball with impact to the middle of the field with the potential to grow into a 25-plus home run threat. He did struggle more against sliders and curveballs throughout the 2025 circuit, and will need more reps against high-quality spin. Peterson has turned in average run times in workout environments, but he’s more of a fringy runner in games and he’s also a bit heavy-footed at third base. He’ll need to improve his footwork, actions and hands to stick at the hot corner, but if he’s able to make those improvements he does have a plus arm that would fit nicely at the position. If not, he would still have the power to profile as a corner outfielder or first baseman. Peterson pitches, as well, throwing strikes with a fastball he can run up to 94 mph and pairing it with a sharp, biting slider in the low 80s that has tight rotation. His pro upside is greater as a hitter. He’s committed to Texas and could be a tough sign, but fits in the 2-5 round range on talent.” – Baseball America
Here’s the one they’ve been saving for, Beau Peterson is a HUGE swing. Shocker, advanced approach, but also a good hit tool and extremely strong pic.twitter.com/V6mQPIJvBa

Peterson will be another overslot signing if the Astros can secure him.
