Boston leads the series three games to none heading into Sunday night. The Red Sox beat New York 4-1 on Saturday. A win Sunday would give Boston its first four-game winning streak of the season. For the Yankees, a loss would mean their first series sweep of 2026.
First pitch is scheduled for 7:20 p.m. ET at Fenway Park. According to CBS Sports, this marks the 2,335th all-time meeting between the two franchises. The Yankees have won 54.6 percent of those matchups across their history.
Sonny Gray takes the ball for Boston. He enters at 9-1 with a 2.95 ERA, one of the stronger lines in the American League this season. Carlos Rodon starts for New York, sitting at 4-2 with a 3.70 ERA.
Neither pitcher has had recent success against Sunday's opponent. Gray has allowed nine earned runs over his last 11.1 innings against New York, posting a 7.15 ERA in those outings. Rodon struggled against the Red Sox last season, putting up a 5.40 ERA across four starts. Sunday will be his first start against Boston in 2026.
Boston is listed as a -113 favorite for the game. The over/under sits at eight runs. CBS Sports noted that a computer model from SportsLine, after simulating the game 10,000 times, projects 8.5 combined runs and favors the over. Since the start of 2025, the over has gone 17-8-1, a 68 percent rate, in Yankees games when New York is not favored. Boston's recent Sunday games have also trended high-scoring, with the over going 4-2 in the Red Sox's last six Sunday contests.
The series has unfolded entirely in Boston's favor through three games, an unusual position for a Yankees team that entered the week at 48-34, one of the better records in the American League. How New York responds in the finale, with its unbeaten streak in series on the line, sets up Sunday night as one of the more consequential regular-season games of the week.
