Houston Astros Prospect Profile: Juan Sierra
Juan Sierra – OF
HT/WT: 6’2”/208 | Bat/Throw: R/R | School/Country: Dominican Republic | DOB: 12/08/05
Overview:
Sierra didn’t come with the typical large bonus that you see international prospects command, signing for just $67,500 in 2023. But he has progressed through the system and made it stateside last year. The 20-year-old hit .289 with a .804 OPS in 2025 for the FCL Astros. Sierra is well built at 6’1″ and 205 lbs. He has a simple swing that allows him to make contact without having to jeopardize power. Sierra also possesses a big arm, the prototypical fit for right field. 2026 could be a huge year for him as he makes his way to full-season for the first time. Sierra is performing well in 2026 hitting .253 with 9 doubles and 9 home runs through 52 games in Fayetteville.
