6. Betting Interpretation / Final Lean

Final Lean & Betting Takeaway

STEP-BY-STEP BETTING ANALYSIS:

STEP 1: Check ALL individual batters for prop opportunities
Tyler O'Neill (.213 → .274, +61 points) does not meet the xBA > 0.300 threshold, thus no lean. Bryce Harper (.270 → .320, +50 points) exceeds both criteria, making him a potential lean.

STEP 2: Check team strikeout rates for pitcher props
Neither team's projected strikeout rate against the opposing pitcher exceeds 25% with a significant increase, so no lean on strikeout props.

STEP 3: Report findings
Our final lean would be on Bryce Harper - his .320 xBA against Kremer's arsenal is well above our .300 threshold with a significant +50 point boost. No significant strikeout prop edges meet our betting threshold in this matchup.
