Swing and miss stuff is the foundation of strikeout production, and his is the foundation of tonight's lean. The split-finger (46.4% whiff) is the put away offering when he needs it. The 10.71 K/9 is the season long anchor. Take Zack Wheeler over his K prop. > **Dig deeper into pitcher arsenals** on the [Pitching Stats dashboard](/mlb/pitching-stats): see pitch mix, whiff rates, and velocity for every starter. ## Pick 2: Kyle Harrison, MIL vs SEA LHP | 114 K on season | American Family Field *114 K · 11.02 K/9 · 29.0% whiff · 2.99 ERA · 1.13 WHIP · 22.0% opp K rate* Kyle Harrison's 11.02 K/9 puts him in elite strikeout territory, the kind of arm that punches out a batter every nine pitches he's in the game. Tonight against SEA he keeps adding to the season total. The 29.0% whiff rate underneath confirms the stuff is real, not BABIP fueled. The 4-seam fastball (30.0% whiff) is the put away offering when he needs it. Ride Kyle Harrison to clear his K number. ## Pick 3: José Soriano, TOR vs TB RHP | 134 K on season | Tropicana Field *134 K · 9.05 K/9 · 31.2% whiff · 3.16 ERA · 1.25 WHIP · 22.0% opp K rate* When swings result in whiffs at this rate (31.2%), Ks follow. José Soriano brings exactly that profile against TB. The curveball (46.6% whiff) is the put away offering when he needs it. The 9.05 K/9 is the season long anchor. José Soriano is my strikeout lean tonight. ## Honorable Mentions - **Braxton Ashcraft** (PIT) vs DET: 9.89 K/9, 26.2% whiff, 3.82 ERA, 155 K - **Carlos Rodón** (NYY) vs BAL: 10.15 K/9, 28.8% whiff, 3.30 ERA, 52 K - **Kevin Gausman** (CHC) vs CWS: 8.94 K/9, 26.9% whiff, 4.53 ERA, 138 K ## Related Guides - [MLB Stats Explained](/blog/mlb-stats-explained) - [Hitter vs Pitcher Matchup Guide](/blog/hitter-vs-pitcher-matchup-guide) - [MLB Weather Betting Guide](/blog/mlb-weather-betting-guide) ## Before You Lock Check the [Pitching Stats dashboard](/mlb/pitching-stats) for full arsenal breakdowns and the [Hitting Stats page](/mlb/hitting-stats) for pitch mix analysis showing which lineups are most vulnerable to certain pitch types.
