Clarke Schmidt, a Yankees pitcher, returned from injury and pitched a strong game, helping his team defeat the Cubs 2-0.
Schmidt, who had not pitched in a major league game since May, showed no signs of rust, limiting the Cubs to only four hits.
The Yankees' victory marks their 32nd consecutive winning season, tying the second-longest streak in all four major pro sports.
With several strong starting pitchers, the Yankees face a pleasant problem of deciding how to deploy their pitching staff for the upcoming playoffs.
