The control differential in this pitching matchup tells a clear story — McGreevy’s 1.88 BB/9 rate against Boyle’s 4.85 BB/9 creates a massive edge the moneyline hasn’t fully absorbed, especially with the Rays missing two everyday contributors on the IL.
I’m riding St. Louis based on one glaring mismatch: pitching control. Michael McGreevy brings something Joe Boyle simply doesn’t — the ability to consistently throw strikes. McGreevy’s 1.88 BB/9 rate last season versus Boyle’s awful 4.85 BB/9 creates a nearly three-walk differential per nine innings. That’s not a small edge; that’s a chasm.
Here’s what really gets me excited about this spot. McGreevy logged 95.2 innings in 2025 with a serviceable 4.42 ERA and 1.25 WHIP, nearly doubling Boyle’s 52-inning sample. The experience gap shows up in WAR: McGreevy at 0.65 versus Boyle’s negative 0.23. While McGreevy provides stability with his 5.46 K/9, Boyle’s 10.04 K/9 comes with those massive command issues that make him a ticking time bomb on the road.
The Cardinals just proved they can explode offensively with that eight-run sixth inning comeback Thursday. When you’re facing a pitcher who walks nearly five batters per nine innings, those momentum swings become inevitable. In neutral Busch Stadium (1.00 park factor), this becomes purely about who can execute — and McGreevy has the clear track record.

| Starters | Joe Boyle (TB) vs Michael McGreevy (STL) |
| Moneyline | Rays -108 / Cardinals -112 |

Tampa Bay’s injury situation makes this even more appealing. Losing Gavin Lux (.269 AVG, .724 OPS) and Taylor Walls removes their best contact hitter and everyday shortstop. What’s left is a lineup featuring Justyn-Henry Malloy (.221 AVG, .654 OPS) and Matt Thaiss (.218 AVG, .638 OPS) — guys who struggle for consistent contact against quality stuff.
But here’s what worries me about Boyle: that 10.04 K/9 rate. If he somehow finds the strike zone early, this Cardinals lineup could get caught chasing. We saw them be patient Thursday, but that was against relievers in late-game situations. Starting fresh against a power arm requires a completely different approach, and Boyle’s strikeout ability could neutralize St. Louis if he gets hot.
The reality is McGreevy doesn’t blow you away with stuff, but his 1.88 BB/9 rate means he’ll challenge hitters in the zone. After watching the Cardinals pile on eight runs in one inning Thursday, I trust this lineup to capitalize when Boyle inevitably falls behind in counts. Jose Fermin (.283 AVG, .793 OPS) provides the contact consistency, while Lars Nootbaar (.234 AVG, .686 OPS, 13 HR) and Ramon Urias (.241 AVG, .675 OPS, 11 HR) bring legitimate run production.
I considered the run line initially given that massive -194 price on Cardinals +1.5, but the 7.5 total suggests oddsmakers expect a competitive game. Even with control problems, Boyle’s strikeout stuff could keep this close enough to make laying 1.5 runs dangerous. The moneyline at -112 offers cleaner value where McGreevy’s consistency advantage should eventually show up.
That 2.97 BB/9 differential between these starters is the story here. McGreevy works ahead in counts while Boyle battles command issues on the road. The Cardinals are 1-0 with momentum from that comeback win, playing at home where they just demonstrated they can explode offensively when opposing pitchers lose the zone.
Pick: St. Louis Cardinals -112
I’m backing the pitcher who throws strikes and the lineup that just proved it can capitalize on mistakes. McGreevy’s control advantage in this matchup is too significant to ignore at this price.
