Forecasters say a 93% rain chance and thunderstorms could force a late start as Boston tries to extend its 14-game winning streak.
On Tuesday, July 21, 2026, the Boston Red Sox postponed their game against the Baltimore Orioles at Fenway Park due to torrential rain, halting the club's pursuit of a 15th consecutive victory.
Boston currently holds a 14-game winning streak, aiming to tie the franchise's longest-ever victory run established in 1946 by a team led by Ted Williams.
AccuWeather described the storm as "heavy," with precipitation odds reaching 93% as the National Weather Service issued flood watches across the region.
The Red Sox and Orioles will now play a split doubleheader Wednesday to make up the contest, with games scheduled for 1:35 p.m. and 7:10 p.m.
Assuming the weather clears, Boston will start right-hander Eduardo Rivera against Baltimore's Kyle Bradish, who holds a 6.75 ERA in 10 career starts against the Red Sox.
