Miguel Sime Jr. Dominates with New Slider in Spring Breakout

In a spring training game at Roger Dean Chevrolet Stadium, Nationals’ 18‑year‑old Miguel Sime Jr. posted a dominant 3.2‑inning, scoreless outing, striking out nine and throwing 44 of 62 pitches for strikes. The right‑hander’s new gyro slider, now his best pitch, accounted for 50% of his deliveries and produced a 76% whiff rate. Sime’s fastball remains powerful at an average of 99.2 mph, but the slider has become his most trusted weapon this spring. goldparty.lat
