Manoah’s six shutout innings had the usual peaks and valleys, including a stretch of four walks in six batters, but the 24-year-old flashed a changeup that could unlock an entirely different tier of his potential. It was on full display against Anthony Rizzo, the second batter he faced. On Monday, Manoah threw his changeup for 17% of his pitches, roughly doubling his usage. If that sticks, it’s a pitch that opposing hitters need to respect in every at-bat, not just an afterthought. This all leads to longevity.
