Pick 1: Taj Bradley, MIN vs LAA

190 K · 10.36 K/9 · 27.1% whiff · 3.81 ERA · 1.25 WHIP · 22.0% opp K rate
Top K play tonight. Taj Bradley's split-finger is a put away pitch, a 37.7% whiff rate on the season. He throws it 20% of the time, which means LAA's hitters see it constantly.
The 27.1% whiff rate underneath confirms the stuff is real, not BABIP fueled. The 10.36 K/9 is the season long anchor. Taj Bradley is the K play I trust most in this spot.

Pick 2: Kyle Harrison, MIL vs PIT
LHP | 134 K on season | PNC Park
134 K · 10.94 K/9 · 28.0% whiff · 3.98 ERA · 1.31 WHIP · 22.0% opp K rate
Kyle Harrison's 10.94 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 PIT he keeps adding to the season total.
The 28.0% whiff rate underneath confirms the stuff is real, not BABIP fueled. The slurve (28.7% whiff) is the put away offering when he needs it. Ride Kyle Harrison to clear his K number.
Pick 3: Nolan McLean, NYM vs PHI
RHP | 184 K on season | Citi Field
184 K · 9.96 K/9 · 24.3% whiff · 3.24 ERA · 1.18 WHIP · 22.0% opp K rate
9.96 K/9 is among the best in the game. Nolan McLean faces PHI tonight, and if the strike zone cooperates, the K total piles up fast.
The curveball (37.6% whiff) is the put away offering when he needs it. Nolan McLean is the K play I trust most in this spot.
