6. Betting Interpretation / Final Lean

Final Lean & Betting Takeaway

STEP-BY-STEP BETTING ANALYSIS:

STEP 1: Check ALL individual batters for prop opportunities
Jr. Witt (.294 → .316, +22 points) = LEAN ✅ (meets both criteria)
Maikel Garcia, Jac Caglianone, Adam Frazier, and Freddy Fermin do not meet the criteria as their xBA falls below .300 or the boost is less than 20 points.

STEP 2: Check team strikeout rates for pitcher props
Neither the Royals nor Marlins exceed a 25% projected K-rate with an increase of over 4%, so no lean on strikeout props.

STEP 3: Report findings
Our final lean would be on Jr. Witt - his .316 xBA against Alcantara's arsenal is well above our .300 threshold with a significant +22 point boost.
