The Boston Red Sox have recently won 10 games in a row, marking their longest winning streak since July 2018. This 10-game winning streak was completed by sweeping the Tampa Bay Rays in a four-game series around mid-July 2025. Historically, the longest winning streak in Red Sox history is 15 games, set in 1946. But as of now, their active winning streak stands at 10 games in a row.
