The Toronto Blue Jays' longest winning streak in the 2025 season was 10 games in a row. This streak ended with a 1-2 loss to the Chicago White Sox. While the franchise record for the longest winning streak is 11 games, set five different times in history, the Jays' current season high is 10 consecutive wins.
More recent wins show a streak of 6 games in a row as of mid-September 2025, but not exceeding the 10-game streak from earlier in the season.
Therefore, the maximum number of games the Jays won consecutively in 2025 is 10.
