A total of 9 at Great American Ball Park looks calibrated for a healthy Athletics lineup — one that no longer exists. With Kurtz, Langeliers, Gelof, and Kuroda-Grauer all on the IL simultaneously, Oakland’s offensive contribution to this run environment is dramatically lower than the posted number reflects, and J.T. Ginn’s 3.46 ERA widens the pitching gap further.
J.T. Ginn vs. Brady Singer: Athletics at Cincinnati Reds Betting Preview
The posted total of 9 at Great American Ball Park looks reasonable for two offenses hovering around 4.1–4.4 runs per game. But that 9 was almost certainly calibrated against a healthy Athletics lineup, and that version of Oakland no longer exists. Nick Kurtz, Shea Langeliers, Zack Gelof, and Joshua Kuroda-Grauer — four of their five listed top hitters — are all on the IL simultaneously. This isn’t a dented roster. It’s a gutted one.
The core betting tension here isn’t whether Cincinnati wins. It’s whether the combined run environment, after accounting for Oakland’s catastrophic injury situation and J.T. Ginn’s legitimate pitching edge, can realistically clear 9. My read says it can’t, and the Under at -115 is the cleanest expression of that.
Brady Singer’s volatility is the honest counter-argument. A 4.35 ERA and 21 home runs allowed through 107.2 innings is a real blowup risk against a Reds lineup that hit 145 home runs this season. But Oakland’s lineup, even at Singer’s expense, is so depleted that the away-side contribution to this total is dramatically lower than the market implies.

Why This Number Is Off
The market is doing its job pricing the park factor at 1.10. Great American Ball Park inflates run scoring, and the book knows that. Singer’s track record of surrendering 21 home runs in 107.2 innings is also baked in — the Reds’ -134 moneyline reflects the starting pitching gap. The 9-total is a defensible number against a functioning Athletics offense.
Here’s where I think the market is slightly wrong: Oakland’s OPS of .722 at full strength already ranks them as a below-average offensive unit. Strip out Kurtz (.879 OPS, 21 HR), Langeliers (.829 OPS, 23 HR), Gelof (.802 OPS), and Kuroda-Grauer (1.019 OPS) — all on the IL — and what remains is a lineup built around Donovan Walton hitting sixth, Jeff McNeil at first base, and Tommy White at third. The projected lineup features Lawrence Butler and Jacob Wilson at the top, and Wilson’s xwOBA of .306 against right-handed pitching doesn’t inspire much fear.
The honest acknowledgment: Singer’s sinker sits at only 91.4 mph with a .366 xwOBA against it — his primary pitch is hittable, and the Reds’ bullpen carries a shaky profile with multiple relievers already on the IL. A multi-run inning from Cincinnati is plausible. But the under needs the combined total to stay under 9, and with Oakland this compromised, their contribution to that total is minimal.
What Separates the Pitching
The gap between these two starters is real and meaningful. J.T. Ginn carries a 3.46 ERA and a 3.07 WAR through 109.1 innings — he’s been one of the more consistent starters in the American League this half. His arsenal centers on a sinker at 34.6% usage (93.6 mph, 20.1% whiff rate, .312 xwOBA against) complemented by a changeup that is genuinely difficult to square: 19.8% usage, 33.3% whiff rate, and a .221 xwOBA against makes it one of the more effective offspeed offerings in the league. His slider checks in at a .250 xwOBA against with a 31.0% whiff rate. Ginn generates soft contact and limits traffic.
Against a Cincinnati lineup led by Elly De La Cruz (.475 xwOBA, 9.0% barrel rate) and Sal Stewart (.412 xwOBA), Ginn will face genuine threats at the top of the order. De La Cruz’s numbers against right-handers (.473 xwOBA) confirm he can hurt any pitcher. But even with that exposure, Ginn’s changeup and slider profile the kind of pitcher who limits crooked innings — he keeps hitters off-balance rather than overpowering them.
Brady Singer is the contrast. His 5-10 record and 4.35 ERA aren’t fluky — they reflect a pitcher leaning heavily on a sinker (48.1% usage, 91.4 mph) that produces a .366 xwOBA against. His sweeper (39.6% whiff rate, .290 xwOBA) is a legitimate weapon, but his four-seamer produces a .474 xwOBA and he’s allowed 21 HR in 107.2 innings. Against a full Athletics lineup, Singer would be a genuine risk. Against this gutted version of Oakland, his shakiest qualities are less likely to be exposed — the matchup-level damage simply isn’t there.
The Pushback
The strongest argument against the Under starts with this park. Great American Ball Park plays at a 1.10 park factor — that’s not trivial. When both bullpens enter the game, the run-scoring environment opens up, and a late-inning unraveling from Singer’s replacement arms (Cincinnati’s own bullpen is depleted, missing Graham Ashcraft and Tony Santillan) could push the Reds past what the front half of the game allows.
The Reds’ lineup is genuinely dangerous. Stewart hit his 24th homer Sunday and is producing at a .412 xwOBA clip. Stephenson (.432 xwOBA vs. right-handers) and Bleday (.431 xwOBA vs. RHP) give this order real depth. The numbers suggest a Reds scoring range of 4–6 runs on their own, which leaves little margin. If Singer serves up two early home runs — entirely consistent with his 21-HR pace — and the A’s cobble together even a couple of runs off a fatigued bullpen, this total gets there.
There’s also the raw projection to acknowledge. The aggregated run-environment estimate comes out around 10.1 — above the posted 9. Singer’s volatility, the park factor, and bullpen exposure are all real inputs into that number. This is a moderate-confidence play, not a lock.
Run Environment & Game Shape
When I map Ginn’s arsenal against Cincinnati’s top of the order, the realistic Reds scoring range is 4–6 runs. De La Cruz and Stewart are dangerous enough that Ginn can’t cruise, but his .221 changeup xwOBA and .250 slider xwOBA give him the tools to strand runners. Cincinnati scores — the question is how much.
Oakland’s projected contribution is the crux. With Kurtz, Langeliers, Gelof, and Kuroda-Grauer all watching from the IL, the A’s realistically project for 2–4 runs against Singer. That’s not a lineup that hangs four or five on anyone. Their recent numbers back this up — outscored 32-7 by Detroit over the last three games, a stretch that admittedly involved different pitching but underscores just how broken this offense is right now.
A realistic game shape: Cincinnati 4–6, Oakland 2–4. That combined ceiling lands at 8–9, right at or just under the number. The under at -115 only needs the game to stay in that range, and with Oakland’s lineup this depleted, there’s no credible path to the away side hitting enough to consistently push this total over 9. Ginn’s soft-contact profile limits the ceiling on what Oakland surrenders, and an A’s offense missing four of its best five hitters cannot realistically compensate for Singer having a clean-enough night.
Joe Jensen’s Pick
The under at 9 is the play. Oakland’s offense is so compromised by injury that even a pedestrian Singer start keeps the combined total manageable. Ginn’s changeup (.221 xwOBA against) and slider (.250 xwOBA against) are legitimate weapons against a lineup built around castaways, and the A’s have no credible counter to a competent pitching performance. The park factor is real and Singer’s volatility is a live concern, but neither changes the fundamental math: this is a 7–9 run game, not a 10+ one.
Bet: Under 9 (-115) — 2 Units
