The station also airs any Boston Red Sox games that are part of Fox's Major League Baseball telecasts. Owing to Fox's exclusive coverage of the World Series since 2000, WFXT has carried every Red Sox championship in the television era (2004, 2007, 2013, and 2018). It also served as the team's primary over-the-air broadcaster for three seasons from 2000 to 2002. WFXT also carried a package of weekday afternoon Red Sox spring training games, produced by NESN, in 2018 and 2019. As mentioned above, it carried Celtics games under the team's ownership in the early 1990s.
