On July 1 the Red Sox were ten games under .500 and their World Series contracts traded at around a penny, priced alongside teams already planning for 2027. Today that number is 9.7%, up nearly tenfold in five weeks.

Boston has won 24 of its 28 games since the calendar flipped to July, outscoring opponents by 56 runs along the way. Buried in that stretch was a 15-game winning streak that tied a franchise record set in 1946 and stands as the longest in the majors since 2021. A team that looked finished in June is now the hottest club in baseball.

Red Sox playoff chances after a 24-4 turnaround

On June 24 the Red Sox were 32-46, 15.5 games adrift in the AL East and six back in the wild card race with eight teams to climb past. The surge under interim manager Chad Tracy, who replaced Alex Cora in April, has carried them to 61-51, the No. 2 AL wild card and within 5.5 games of the division-leading Rays. During the streak alone, their playoff probability jumped from 13.4% to 64.7%, the biggest move in baseball.

Tuesday night brought a sixth straight win, a 14-2 demolition of the White Sox built on a Caleb Durbin grand slam and two solo home runs from Wilyer Abreu, leaving Boston 8-2 over its last ten games. An offense that produced 3.96 runs per game before the streak is averaging nearly six during it.

Red Sox winning streak

A few figures capture how extreme five weeks of baseball have been:

  • 24-4 since July 1, the best record in the majors over that stretch
  • A 15-game winning streak from July 3 to July 22, tied for the longest in franchise history
  • Nearly 6 runs per game during the streak, up from under 4 beforehand
  • 61-51 overall, holding the No. 2 AL wild card, 5.5 games behind Tampa Bay
  • A World Series probability that has climbed from roughly 1% to 9.7%

Who turned Boston's season around?

The individual stories underneath the run explain why traders are treating it as more than a heater. Sonny Gray has gone 12-1 with a 2.48 ERA, Willson Contreras has produced 22 home runs, 66 RBIs and a .948 OPS in the middle of the order, and rookie Jake Bennett has gone 4-1 with a 1.17 ERA over his last six starts since arriving from Triple-A. Aroldis Chapman has anchored the late innings with a 1.93 ERA across 34 appearances.

The entire 24-4 stretch has come without two of the roster's cornerstones, with Garrett Crochet sidelined since late April and Roman Anthony out since early May. Absences that helped sink the first half instead spread responsibility across the clubhouse, and Tracy's even temperament has been credited by his own players with keeping a young roster steady while the winning compounded.

Where the Red Sox World Series probability stands

For all the momentum, the market has not lost its head. The Dodgers remain clear favorites at 38.3%, the position you would expect from the leaders of the NL West. The Yankees sit second at 10.8% and the Red Sox have climbed to third at 9.7%, with Yes contracts trading at 9.6 cents. Since prices in these markets are probabilities written as money, traders collectively give Boston a one-in-ten chance of finishing as Red Sox World Series champions this fall, up from one-in-a-hundred five weeks ago.

More than $45.3 million has traded on this championship market, enough to make the repricing hard to dismiss as thin-market noise. Real money moved Boston from an afterthought to the third line on the board.

The case for caution

A 9.7% probability still means the market expects someone else to win nine times out of ten, and Boston's situation supports the restraint. The Red Sox trail the Rays, owners of the best record in the American League, by 5.5 games in their own division, which points their likeliest October path through a best-of-three wild card round where hot teams die young. Gray will not finish the year 24-2, the offense will cool from six runs a game, and two months remain for the injury list to bite again.

The counterpoint is that the market was not wrong to move, it was wrong to start so low. A roster that swept series from the Rays, Yankees and Dodgers while winning 24 of 28 was never a true 1% team. Whether the fair number today is 8% or 12% is a legitimate argument. That it is no longer 1% is not.
