6. Betting Interpretation / Final Lean

Final Lean & Betting Takeaway

STEP-BY-STEP BETTING ANALYSIS:

STEP 1: Check ALL individual batters for prop opportunities
Xander Bogaerts (.268 → .302, +34 points) meets the criteria with an xBA over .300 and a boost above +20 points. Brady House (.258 → .321, +63 points) also meets our criteria for a strong lean.

STEP 2: Check team strikeout rates for pitcher props
Neither team's projected K-rate meets the threshold for a strikeout prop lean, as both teams' projected K-rates are below 25% and the increase is under 4%.

STEP 3: Report findings
Our final lean would be on Xander Bogaerts — his .302 xBA against Parker's arsenal is well above our .300 threshold with a significant +34 point boost. Additionally, Brady House presents a strong lean with his .321 xBA against Darvish, showing a +63 point increase.
