Carson Palmquist carries a 7.11 ERA and 1.58 WHIP into just his second career MLB start, backed by a Washington bullpen missing three arms on the injured list. The 9.5 total has moved, but a starter who hasn’t proven he can get through a lineup once — facing a Yankees lineup with an xwOBA weapon in James Wood — leaves the number sitting in a precarious spot.
Ryan Weathers vs. Carson Palmquist: New York Yankees at Washington Nationals Betting Preview
The story of this game isn’t the Yankees’ 12-run eruption against Tampa Bay on Thursday — that result is yesterday’s news. The story is who’s toeing the rubber for Washington tonight. Carson Palmquist is making just his second career MLB start, carrying a 7.11 ERA and 1.58 WHIP across 6.1 innings of work. That’s essentially a debut sample, and yet the total sits at 9.5, with the Over priced at -124. The market has moved, but not enough.
Layer in the Nationals’ bullpen situation — three arms on the injured list in Mitchell Parker (60-Day IL), Richard Lovelady (15-Day IL), and Brad Lord (15-Day IL) — and the likely scenario of a short Palmquist outing becomes genuinely alarming for run prevention. When a shaky starter gets pulled in the third or fourth inning, someone has to eat those innings. Washington’s available relief corps will be leaned on heavily, and early.
The secondary hook is Washington’s offense. This isn’t a lineup the Yankees can ignore. James Wood (.948 OPS, 25 HR), Luis García Jr. (.894 OPS, 20 HR), and CJ Abrams (.872 OPS, 20 HR) give the Nationals genuine run-scoring firepower against a Yankees starter in Ryan Weathers who has surrendered 16 home runs in 92.1 innings this season. The total is asking you to trust two functional pitching performances. Only one of these starters comes close to qualifying.

Why This Number Is Close — But Slightly Off
The market set this at 9.5 for defensible reasons. Nationals Park plays at essentially a neutral 0.98 park factor, so there’s no environmental inflation to account for. The numbers project a combined 9.1 to 9.2 runs — which means the Under (+102) is actually the sharper mathematical position if you trust the projection cold.
But that projection is built on assumptions the Palmquist situation disrupts. A 7.11 ERA over 6.1 innings is not a baseline — it’s a warning sign. The Statcast profile on Palmquist’s arsenal shows a four-seam fastball sitting at just 91.5 mph, a sweeper at 74.5 mph generating a 34.8% whiff rate, and a sinker at 90.9 mph. That sweeper whiff rate looks decent in isolation, but 34.8% against major league hitters is not a true swing-and-miss weapon when the fastball behind it sits at 91.5 — hitters can sit on the heater and still recognize the breaking ball without much velocity differential to process. The four-seamer’s xwOBA-against of .233 looks passable, but that’s in a tiny sample against hitters who may not have a book on him yet.
The legitimate case for the Under is this: if Palmquist gets pulled early, Washington’s available bullpen arms could actually suppress the Yankees — New York’s offense has been legitimately cold, scoring zero runs in the three games prior to Thursday’s outlier blowout. One 12-run game doesn’t reset a prolonged cold stretch. That’s the honest pushback, and it’s real. But placing the Under on a game where a pitcher with a 7.11 ERA starts is the wrong side of a structural mismatch.
What Separates the Pitching
The gap between these two starters is significant, and it runs in a direction that favors the Over.
Ryan Weathers is a flawed but functional major league starter. His sweeper sits at 81.9 mph and generates a 44.5% whiff rate with a .263 xwOBA — that’s a legitimate put-away weapon. His changeup at 85.7 mph adds another layer at 34.4% whiff. The problem is his four-seam fastball: 96.2 mph, but an xwOBA-against of .429 — hitters are doing damage when they get to it. His sinker xwOBA sits at .406. He’s a pitcher who generates swings and misses with his secondary stuff but gets hurt when hitters sit fastball. Washington’s power trio of Wood, García, and Abrams all carry strong xwOBA figures against right-handed pitching. James Wood’s overall xwOBA is a staggering .585 with an 11.4% barrel rate — and against righties, that number climbs to .617. Weathers’ 16 home runs allowed in 92.1 innings tells you what happens when the fastball catches too much plate.
Carson Palmquist, by contrast, hasn’t demonstrated the ability to navigate a major league lineup for more than one trip through the order. His arsenal lacks velocity — the four-seamer at 91.5 mph, a sweeper at 74.5 mph — and his WHIP of 1.58 in limited work reflects hitters finding ways on base at a high clip. Ben Rice carries an xwOBA of .451 and has crushed right-handed pitching (.481 xwOBA vs. RHP) — a direct mismatch against a pitcher who hasn’t proven he can retire quality hitters consistently. The type of innings these two create diverges sharply: Weathers creates a mix of swing-and-miss and hard contact, while Palmquist, in his brief track record, has created baserunners and trouble. In a neutral park, that distinction is the core of the Over case.
Run Environment & Game Shape
Nationals Park’s 0.98 park factor means what happens in this game is almost entirely a product of the pitching matchup — there’s no wall in left-center inflating fly balls, no sea-level air juicing exit velocity. The run environment here is shaped almost exclusively by who’s on the mound, and on one side of this game, that is a severe liability. Palmquist’s 7.11 ERA and 1.58 WHIP aren’t fluky — a 91.5 mph fastball with a sweeper that tops out at 74.5 mph gives a major league lineup too much time to read and react. Even Weathers’ vulnerability to the fastball becomes secondary when you consider that the Yankees don’t need to manufacture runs against Palmquist; they just need to put balls in play hard. Rice (.481 xwOBA vs. RHP), Wood (.617 xwOBA vs. RHP), and a depleted Washington bullpen forced into extended work create a clear structural case for runs to pile up on both sides. A neutral park doesn’t suppress scoring when one starter can’t hold a lineup — it just removes the excuse. The juice at -124 requires a 55.4% break-even, and given a one-sided pitching mismatch with bullpen depth stripped away on the Washington side, I’m comfortable clearing that threshold.
The Bet: Over 9.5 (-124), 2 units, moderate confidence. Two broken pitching situations — one structurally, one by pure inexperience — in a neutral environment with bullpen depth missing on the side that needs it most. The liability is concentrated on the Palmquist start, and the Yankees’ lineup, even in a cold stretch, is built to punish the kind of fastball he’s throwing.
