Background
Barahona, on the southern coast of the Dominican Republic, has been producing baseball talent for generations — and Lao is its latest export. He worked his way through the academy system and the minor leagues, sharpening his arsenal before earning his shot at the majors in 2025.
Professional Career
Lao’s 2025 season was split between two organizations. With the Washington Nationals, he went 1-0 with a 3.52 ERA, 5 strikeouts, and a 1.17 WHIP in 7.2 innings — a solid introduction to big-league hitters. His stint with the Seattle Mariners was rougher: an 8.10 ERA in 3.1 innings, a reminder that the adjustment to MLB is rarely a straight line.
Combined, his 2025 MLB line reads: 1-0, 4.91 ERA, 9 strikeouts, 1.45 WHIP in 11.0 innings. Uneven, yes — but the strikeout rate and the Washington sample give you something to hold onto.
Winter Ball: A Different Story
If you want to understand where Lao’s ceiling might be, watch him pitch in the Dominican Republic. With the Leones del Escogido in LIDOM, he has been nearly untouchable. In the 2026-27 season, he went 3-0 with a 0.00 ERA and 9 strikeouts in 16.0 innings — one of the most dominant stretches any pitcher has put together in the league this winter.
The previous winter (2024-25) was productive too: 2 wins, 1 save, 7 strikeouts, and a 3.94 ERA in 16 appearances across 16.0 innings. The trend line is pointing up.

Worth Knowing
Lao’s 2026-27 LIDOM campaign — 3 wins, 0.00 ERA, 9 strikeouts in 16 innings — isn’t just a good stretch. It’s the kind of dominant winter work that tells a pitcher’s real story between MLB seasons. In his home country, Sauryn Lao isn’t a prospect anymore. He’s a proven arm.
