JUPITER, Florida – The young talent continues to shine in spring training. On this occasion, the Dominican Miguel Sime Jr., at just 18 years old, left everyone speechless by reaching impressive speeds on the mound during Spring Breakout. The Washington Nationals prospect starred in one of the most outstanding moments of the game by facing JJ Wetherholt, recognized as one of the most promising talents in baseball. In a full count, Sime threw a 100.8 mph fastball that generated such a strong swing and miss that it even dislodged the batter’s helmet. Despite starting the inning with a 3-0 disadvantage, the young pitcher demonstrated calm and recovery ability, combining his repertoire with effective sliders before finishing with his powerful high fastball. Sime’s dominance was not by chance. Of the 21 pitches he threw in the game, nine exceeded 100 mph, solidifying his position as one of the most exciting pitching prospects in the minor leagues. Selected in the fourth round of the 2025 Draft, the Dominican-born pitcher has shown rapid progress, driven by his dedication and consistency in developing his skills.
Sime declared after the match, making it clear that, although his speed is already elite, his focus remains on perfecting his mechanics and control.It’s exactly where I want to be
