Jake Bennett’s 2.74 ERA and 34.1% whiff rate on his changeup make him the most reliable run-suppressor on the board Sunday — yet the Over is still priced at -114 while the Under sits at -106. Dodger Stadium’s mild park factor compounds the lean, and a projected combined total of 8.7 barely clears the posted number. The pricing does the arguing here.
Jake Bennett vs. Emmet Sheehan: Boston Red Sox at Los Angeles Dodgers Betting Preview
After yesterday’s taut 3-2 Red Sox win — Andruw Monasterio’s ground-rule double setting up the go-ahead run — the series shifts to a pitching matchup that tells a very different story than Friday’s 9-4 blowout. The market has settled on 8.5 as the number, and the pricing tells you the books see this as a genuine toss-up on the total. They’re not wrong to be cautious. But when the projected combined total lands at 8.7 and the Under is cheaper to buy, the lean finds itself pretty quickly.
The core thesis here is Jake Bennett. His 2.74 ERA and 0.97 WHIP across 65.2 innings isn’t a fluke — it’s built on exceptional control (11 walks all season) and a changeup that generates a 34.1% whiff rate. He’s the primary suppressor on this run environment, and he’s wildly outperforming what most people expect from a Boston rotation that’s also dealing with meaningful injury attrition. Dodger Stadium’s 0.98 park factor nudges scoring down modestly but consistently. That combination — elite pitcher, mild run-suppressor park, a total barely above the projected number — points toward the Under.
The 9-4 Friday game looks alarming at first glance, but that result was driven by Cole Irvin’s first MLB appearance since 2024 after having his Triple-A contract selected the same day. That’s noise. Today’s pitching card looks nothing like it.

Why This Number Is Close
The books have this number right in a general sense. Eight and a half is a reasonable expectation when you have one elite pitcher (Bennett) offset by one homer-prone starter (Sheehan) backed by a loaded Dodgers lineup. The market is balancing the suppressive case — Bennett’s ERA, the park, Boston’s weak team OPS of .709 — against the legitimate threats on the other side. Ohtani carries a .510 overall xwOBA this season, one of the best quality-of-contact marks in baseball, and his .481 xwOBA against left-handed pitching specifically still makes him as dangerous a matchup as exists. Freeman’s .420 xwOBA and Muncy’s season OPS of .840 give Sheehan’s poor sequencing plenty of fuel.
But here’s where the pricing gives the game away: the Over is sitting at -114, the Under at -106. The market is subtly telling you it expects more than 8.5, not less, or it would equalize the juice. Yet the projected combined total lands at 8.7 — barely 0.2 runs above the number. That’s not enough cushion to pay -114 for the Over. The Under at -106 is the price-correct expression of a game that the numbers see as virtually dead-on the total.
The concern is that an 8.7 projection means we’re riding a razor-thin margin. One Ohtani home run off Bennett swings the entire equation. That’s a real risk, not a theoretical one.
What Separates the Pitching
The gap between these two starters is significant, and it runs in one direction on the run-environment question.
Bennett is operating at a level that makes Boston’s depleted lineup almost irrelevant to the Under case — he just doesn’t give up runs. His four-seam fastball sits 93.0 mph with a 20.3% whiff rate and an xwOBA-against of .308. More importantly, his changeup — deployed 24.7% of the time at 83.4 mph — generates a 34.1% whiff rate and holds hitters to a .164 xwOBA. That pitch alone is an innings-eater and a rally-killer. He’s walked 11 batters in 65.2 innings. Against a Dodgers lineup as disciplined and patient as any in baseball, the ability to throw strikes without issuing free passes is underrated. The Dodgers’ top of the order — Ohtani, Pages, Edman, Freeman — has legitimate pop, but Bennett’s sinker (25.0% usage, .293 xwOBA-against) keeps the ball on the ground and limits multi-run innings.
Sheehan is a different animal. His K-rate is elite — 10.1 K/9 — and his slider generates a 37.5% whiff rate at 86.6 mph with a .252 xwOBA-against, which is genuinely filthy. But his four-seam fastball is getting hit hard (.367 xwOBA-against), and he’s allowed 17 home runs in 92.2 innings. Boston’s lineup, even stripped of Contreras and Mead, has 107 home runs on the season. Wilyer Abreu sits at a .390 xwOBA overall and hit his 16th homer just two days ago. The strikeouts keep Sheehan from complete implosions — you’re not getting 5-run crooked numbers against a 10.1 K/9 pitcher — but the home run exposure means Boston can manufacture a run or two on very little contact.
Net result: Bennett suppresses the higher-projected Dodgers offense, Sheehan keeps Boston from stringing hits together but surrenders the occasional solo shot. The run total on both sides leans low, which is exactly what the Under needs.
The Pushback
I’m not going to pretend this is a comfortable Under ticket. The 0.2-run margin between the projected total and the posted number is about as thin as it gets. The Dodgers just acquired Tarik Skubal at the deadline — it doesn’t affect today’s game, but it signals this is a franchise pushing all-in, and that energy matters in a home environment where Dodger Stadium was loud and engaged all weekend.
More concretely: Ohtani’s .481 xwOBA against left-handed pitching is the number I keep coming back to. Bennett is a lefty, and while his changeup and sinker profile isn’t a traditional fastball-heavy matchup that Ohtani eats alive, the overall quality-of-contact threat is real. His .510 season xwOBA is the best in this game by a significant margin. One swing changes a 4-3 final into a 6-3 final, and that’s not a black-swan scenario — that’s just Shohei Ohtani doing Shohei Ohtani things.
The Dodgers’ lineup depth compounds this. Even below Ohtani, Freeman (.420 xwOBA), Edman (.415 xwOBA vs. LHP), and Pages (.454 xwOBA vs. LHP) give Bennett three legitimate threats before you even get to Hernández and Muncy. Boston’s lineup, meanwhile, is good but not elite — the team OPS of .709 ranks mid-pack, and the injury attrition to Contreras and Mead thins the order further today.
This isn’t a lock. It’s a value play on pricing.
Run Environment & Game Shape
The most likely game shape here is something like 4-3 or 5-3 — a low-scoring, pitching-dominant affair where Bennett holds the Dodgers to two or three runs through five or six innings, and Sheehan’s strikeout ability limits Boston’s damage to a solo shot or a two-run inning at most. Dodger Stadium’s 0.98 park factor doesn’t dramatically alter the equation, but it consistently shaves half a run off the expected environment in games where pitching is already dominant, and Bennett’s profile fits that context perfectly.
The bullpen picture adds a modest wrinkle. Both clubs carry injury-depleted relief corps — Boston’s Chapman is available and has been sharp (27 saves), but the middle innings are thinner. LA’s bullpen has also dealt with losses. That creates the real ceiling risk: if either starter exits early, the run environment can spike. The risk is Sheehan’s HR vulnerability turning a 4-3 game into a 6-3 game off one swing. That’s the shape to watch.
On balance, the combination of Bennett’s elite contact-suppression, the mild park factor, and the juice discount on the Under makes this the right side of a genuinely close number. The 8.7 projection doesn’t scream Under — it whispers it — but at -106, I don’t need it to scream.
Bet: Under 8.5 at -106 — 2 units.
