Final Lean & Betting Takeaway

Arizona's projected K-rate against Burrows (21.0%) does not exceed the 25% threshold required for a lean. Pittsburgh's projected K-rate against Nelson (27.2%) does exceed 25%, but the increase is less than the required 4% from their season average.

No significant statistical edges meet our betting threshold in this matchup.
