2. Pitcher Breakdown

Pitching Matchup: Robbie Ray vs. Andrew Heaney

6. Betting Interpretation / Final Lean

Final Lean & Betting Takeaway

STEP-BY-STEP BETTING ANALYSIS:

STEP 1: Check ALL individual batters for prop opportunities
No batters from either team meet the criteria of having an xBA over .300 with an increase of more than 20 points, leaving us without any strong batting leans.

STEP 2: Check team strikeout rates for pitcher props
Neither team's arsenal K% exceeds 25% with an increase greater than 4%, so there are no clear strikeout prop leans in this matchup.

STEP 3: Report findings
No significant statistical edges meet our betting threshold in this matchup. While there are shifts in projected performance, none cross the critical thresholds needed for a confident betting lean.
