2. Pitcher Breakdown
Pitching Matchup: Michael McGreevy vs. Austin Gomber
Michael McGreevy (STL):
McGreevy brings a diverse arsenal to the mound: Four-Seam (26% usage, 93.0 mph), Sinker (24% usage, 91.8 mph), Sweeper (19% usage, 83.6 mph), Cutter (12% usage, 88.4 mph), Slider (8% usage, 83.6 mph), Changeup (6% usage, 88.4 mph), and Curveball (6% usage, 79.7 mph). This makes him a pitch-mix artist, able to keep hitters guessing. The Rockies lineup averages .263 this season with a projected xBA of .264 against McGreevy's varied arsenal, suggesting they might find some success against him.
Austin Gomber (COL):
Gomber relies on a mix of: Four-Seam (35% usage, 89.0 mph), Curveball (24% usage, 76.0 mph), Slider (17% usage, 82.4 mph), Changeup (16% usage, 80.6 mph), and Splitter (9% usage, 81.1 mph). This combination of pitches lacks overpowering velocity, positioning Gomber as a control and deception pitcher. The Cardinals lineup has a .264 season average but projects to a lower .238 against Gomber’s offerings.

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 above .300 with a boost of more than +20 points.
STEP 2: Check team strikeout rates for pitcher props
The Cardinals' projected K-rate against Gomber is 24.8%, which is an increase of 6.5% from their season average, but it does not exceed the 25% threshold, thus no lean on strikeout props. The Rockies' K-rate against McGreevy falls below their season average, suggesting a contact play, but again, no lean on strikeout props as criteria aren't met.
STEP 3: Report findings
No significant statistical edges meet our betting threshold in this matchup. Without any batter overperforming significantly against the opposing arsenal or the required increase in strikeout rates, this game lacks clear prop betting opportunities.
