Nathan Eovaldi’s 2.1 BB/9 and a Cardinals offense that has scored just one run in the last game present a run-environment picture that cuts in one direction. The total at 7.5 (-122) has absorbed the public lean, but eight-plus IL absences across both rosters and a neutral Busch Stadium haven’t fully filtered into how the market is treating this number.
Nathan Eovaldi vs. Dustin May: Texas Rangers at St. Louis Cardinals Betting Preview
Monday night finished 2-1 — a low-scoring environment at Busch Stadium that set the table for tonight’s middle game. The total sits at 7.5 (-122), and the market’s already pricing in a pitcher-controlled outcome. What it may not be fully pricing in is the gap between the two arms on the mound tonight, the combined depletion across both rosters, and the Cardinals’ recent offensive collapse. The thesis isn’t about Texas winning — it’s about neither team scoring enough to push past 7.5.
The Cardinals have dropped to 3-7 in their last 10 games with a -11 run differential, and they’re trotting out Dustin May with a 4.57 ERA against a Rangers lineup that, while missing Corey Seager, Wyatt Langford, and Josh Smith, still has enough to make May work. On the other side, Nathan Eovaldi‘s profile — just 16 walks in 68.2 innings — is the kind of control that limits damage even when he gives up contact. This is a pitcher’s game built for low totals, not a coin-flip between two offenses that both carry identical .696 OPS marks.

Why This Number Is Close
The market has landed at 7.5 (-122) for good reason. Both offenses post identical .696 OPS figures — among the lower marks in the league — and last night’s game finished 2-1. The books aren’t asleep here; they’ve priced in a low-scoring environment and pushed the juice on the under to reflect genuine market consensus.
The legitimate case for the over rests on May’s ERA and WHIP. At 4.57 and 1.295 respectively, May has been hittable. If the Rangers’ lineup — even a depleted version of it — jumps on him early, the innings can stack up quickly. And the Cardinals have Jordan Walker sitting at a .893 OPS with 15 home runs; one swing can change the shape of a game. The over is priced at +100, which is a market telling you it’s genuinely close.
But here’s the problem: the numbers project a combined score of 8.9, which is already above the total — and projection models tend to lean over because they’re anchored to season-long baselines. The actual game risk skews under when you layer in eight or more IL absences across both clubs, a stadium with a neutral park factor, and a starter on the Rangers side whose profile actively suppresses free baserunners. The -122 juice is steep, but the depletion context gives the under more cushion than the raw number suggests.
What Separates the Pitching
The gap between Eovaldi and May is real, and it shows up in the arsenal data. Eovaldi’s bread-and-butter is his split-finger, thrown 36.5% of the time at 88.4 mph, generating a 29.3% whiff rate and a suppressed .292 xwOBA against. His curveball — used 20.6% of the time — is his best swing-and-miss offering at an elite 37.9% whiff rate and a .182 xwOBA. That combination of a diving splitter and a high-spin curveball is built to generate weak contact and keep runners off base, which explains the 2.1 BB/9. Against a Cardinals lineup that has gone cold — scoring just one run last night and struggling to a 3-7 record in their last 10 — Eovaldi’s precision is a genuine problem.
May operates with more raw stuff but less command of the zone. His 97.0 mph four-seamer leads his mix at 24.8% usage, but it holds hitters to a .329 xwOBA — not dominant. The pitch that actually does damage prevention work is his sweeper: 19.7% usage, 85.9 mph, and a sharp 32.0% whiff rate with a .247 xwOBA. That’s a legitimate weapon. But his cutter and sinker are hittable, and his 1.295 WHIP reflects an arm that regularly allows baserunners. The key redemptive note on May: he’s surrendered only 5 home runs in 61 innings (HR/9 around 0.74), meaning he tends to give up singles and doubles rather than multi-run blasts — limiting the ceiling on any given inning.
Brandon Nimmo’s .484 xwOBA against right-handed pitching makes him the most dangerous Ranger in this matchup, but with Seager, Langford, and Smith out, the protection around the lineup’s top hitters thins considerably. The Cardinals’ best chance to score against Eovaldi runs through Jordan Walker, who carries a .460 xwOBA versus right-handers. Walker’s 7.6% barrel rate and 32.0% hard-hit rate make him the one genuine threat to single-handedly cash the over.
The Pushback
The honest concern is May’s WHIP. At 1.295, he’s been putting runners on at a rate that sets up crooked innings — and a Rangers lineup that’s had some success against right-handers could make a mess of things quickly if the walks and singles start to cluster. Joc Pederson (.372 xwOBA vs. RHP) and Nimmo (.484) at the top of the order give the Rangers legitimate on-base threats even without their middle-of-the-order depth.
There’s also the Walker factor on the other side. Eovaldi’s cutter — thrown 20.8% of the time — generates a .435 xwOBA against, and Walker is exactly the kind of hitter who feasts on elevated cutters. Eovaldi has surrendered 13 home runs in 68.2 innings (1.7 HR/9), which is a real number. One Walker at-bat in a key spot could flip the total on its own.
And yes, the 8.9 combined projection from the numbers is above 7.5 — that gap isn’t nothing. The market’s not wrong to price the over at even money.
But the Cardinals are 3-7 in their last 10 with a -11 run differential. They have at least eight players across both rosters currently on the IL — Texas alone is missing Seager, Langford, Smith, and two relievers on the 15-Day IL, while St. Louis is without Nathan Church and Ramon Urias. The Cardinals’ offense has gone quiet at exactly the wrong time, and Busch Stadium’s neutral park factor doesn’t bail anyone out. The over case requires May to get hit hard AND Eovaldi to have an uncharacteristic control lapse in the same game. That’s a conjunction bet against a pitcher who walks fewer than 2.1 batters per nine.
The edge on the under is modest but directional: two well-matched offenses, a dominant control pitcher leading for Texas, an offense-suppressing environment, and a Cardinals club that can’t buy a run right now. Take the under at 7.5 (-122) for 2 units.
Bet: Under 7.5 (-122) — 2 Units
