MLB Trade Deadline Grades: How Dodgers, Cubs and Red Sox Winners Stack Up Against Brewers, Tigers and White Sox Losers on the World Series Futures Board

The trade deadline moved World Series futures more than any single week of the regular season, and the reason is simple: three teams walked away holding real value while three others watched their odds get worse in real time. Grading these deals is not just an academic exercise for bettors. Every front office decision made before Monday’s 6 p.m. ET cutoff reshaped the futures board, and understanding which grades actually track with betting value separates a sharp read from a lagging one.

Los Angeles, Chicago’s North Side, and Boston delivered the three cleanest letter grades of the deadline. Milwaukee, Detroit, and the South Side of Chicago delivered the other end of that spectrum. Here is how each grade lines up with where the market is pricing them now, and where the value gaps are worth watching.

MLB Trade Deadline Grades: The Winners Bettors Should Be Tracking

Grading a trade deadline for betting purposes means asking one question the highlight shows do not: did this team’s championship equity actually change, and does the current price reflect it? For three teams, the answer is a clear yes.

Los Angeles Dodgers: A+ Grade, Odds Already Reflect It

The single biggest swing of the deadline was the Dodgers landing two-time AL Cy Young winner Tarik Skubal from the Tigers for outfielder Zyhir Hope and pitching prospects River Ryan and Brady Smith. Multiple outlets handed Los Angeles an A+ or A for the return alone, and the fact that the front office did not have to surrender its top-three prospects to get an ace of Skubal’s caliber is what pushes the grade that high. The Dodgers also added left-hander Kris Bubic from the Royals for rotation depth, layering a second useful arm onto the Skubal move without touching the roster’s core.

The market has already baked this in. Los Angeles sits at +150 on DraftKings promo code markets to win the World Series, with some books as high as +160, translating to roughly 41% implied probability by itself — miles ahead of the field. That is not a case of a grade waiting to be priced in. The books moved fast, and the value on the Dodgers as championship favorites is essentially gone unless you got a number before Saturday.

Chicago Cubs: A-/B+ Grade, Odds Still Have Room

If the Dodgers were about adding one elite piece, the Cubs deadline was about adding volume of quality. Chicago brought in starter Kevin Gausman from the Blue Jays, reliever Clay Holmes, starter Braxton Garrett from the Marlins, and reliever Ryan Zeferjahn — a complete rotation and bullpen overhaul that several grading outlets flagged as the single largest amount of total value added by any team at the deadline. The cost included shortstop prospect Jefferson Rojas and catcher Moises Ballesteros, a real price, but one that reflects genuine win-now urgency rather than a scattershot approach.

This is the grade with the most betting daylight attached to it. The Cubs’ World Series number moved from 20/1 on Sunday to 15/1 by Monday, the single biggest odds mover of the entire deadline according to DraftKings’ board. A jump that fast after an A-grade deadline suggests the market is still catching up to how much rotation depth Chicago actually added, which is exactly the kind of gap bettors look for in a futures market that reprices in real time.

Boston Red Sox: A- Grade, Best Value on the Board

Boston’s headline move — acquiring catcher Adley Rutschman from the Orioles for a package built around top pitching and catching prospects including Anthony Eyanson, Kyson Witherspoon, and outfielder Enddy Azocar — is being called one of the most surprising trades of the entire deadline. The Red Sox did not stop there, also adding reliever Erik Miller, outfielder Eli White, and third baseman Curtis Mead from the Rays for left-hander Connelly Early. It is an aggressive, multi-layered deadline built on the back of a 21-4 July that already had Boston trending before the trades even happened.

Here is where the futures value gets interesting. The Red Sox sit at +1400 to +1800 depending on the book — roughly a 6% implied shot — for a team that just landed a top-tier catcher and capped one of the best months in franchise-recent memory with more talent added on both sides of the ball. Among the three top-graded teams, Boston is priced the furthest behind its grade, which makes it the most compelling futures number left on the board for anyone who believes letter grades eventually catch up to championship odds.

MLB Trade Deadline Grades: The Losers and What Their Odds Say

Three teams left Monday with clearly worse rosters or clearly worse value than they started with, and the futures board is already reflecting two of the three.

Milwaukee Brewers: Missed on the Big Fish

Milwaukee reportedly pursued Skubal and came away instead with right-hander Dustin May and reliever JoJo Romero from the Cardinals, plus reliever Antonio Senzatela — a collection of useful depth arms rather than the kind of difference-maker the roster needed. ESPN specifically flagged the Brewers as one of the deadline’s biggest losers for that exact reason: swinging for a true ace and settling for volume. Interestingly, the market has not fully punished them yet — Milwaukee still sits at +900 (as high as +850 on FanDuel), the third-best World Series price in the sport at roughly 9% implied probability, ahead of teams that graded out much better. That gap between a “loser” grade and a top-three futures number is worth watching closely as the season plays out.

Detroit Tigers: The Skubal Return Wasn’t Enough

Detroit’s grade for parting with Skubal ranged from A- to B+ depending on the outlet, largely because of the volume of young talent it got back in Hope, Ryan, and Smith. But that return did not stop ESPN from naming the Tigers the other big loser of the deadline — trading away a two-time Cy Young winner guts a rotation regardless of what comes back in return, and the market is not being kind about it. Detroit’s World Series odds sit at +17500, second-worst among teams that made any move at all, and a stark reminder that prospect grades and championship equity are two very different scoreboards.

Chicago White Sox: The Lowest Grade of the Deadline

The White Sox acquired right-hander Luis Castillo from the Mariners for a package including reliever Seranthony Dominguez, infielder Nolan Jones, and catcher/outfielder prospect Boston Smith. The Athletic handed this trade a D grade outright, questioning the value of surrendering that much talent for a pitcher who has struggled with a 5.06 ERA in recent stretches. Seattle, by contrast, graded out at a B+ for the return. The futures board agrees with the grade — Chicago sits at +3300, buried outside the top ten, and nothing about this move changes that outlook.

What the Grades Mean for World Series Futures Going Forward

The clearest takeaway from grading this deadline against the betting market: not every “winner” grade has been fully priced yet, and not every “loser” grade has fully tanked a number. The Dodgers’ A+ deadline is already reflected at +150. The Cubs’ A-/B+ deadline is still catching up, having just made the single biggest odds jump on the board. And the Red Sox’s A- deadline, backed by a 21-4 July, remains the most disconnected from its price of the three winners — the kind of gap that futures bettors watch closely as a season moves toward October. On the other side, Detroit and Chicago’s White Sox have odds that already match their grades, while Milwaukee’s front-three futures price despite a “loser” label is the one number worth revisiting as the stretch run unfolds.

For bettors weighing new futures positions after the deadline, comparing books matters more than ever given how much movement already happened in a 48-hour window — a FanDuel Promo Code or BetMGM Promo Code offer can be the difference between locking in a number before or after a market adjustment like the ones described above. The Expected Value (EV) Calculator is also a useful way to sanity-check whether a post-deadline futures price still represents real value once the letter grades and the odds board are lined up side by side.
