On May 10, the Red Sox were 23-33. Six weeks later, and things had gotten worse as Boston sat at a season-worst 14 games under .500 (32-46). But on June 23, a modest turnaround began, as the Red Sox closed out the month with a 6-2 record. In July, Boston embarked on a 15-game winning streak, tying a franchise record from 1946 and going 21-4 overall in the month.
