What happened: Boston entered July at 37-47, 13 games out of first place and positioned to sell. It enters August six games back after reversing its deadline posture.
Why it matters: The turnaround gives Boston reason to strengthen its roster instead of shedding talent. Its improved position puts postseason stakes on the remaining schedule.
By the numbers: July record: 21-4. First-place deficit: 13 games entering July, six entering August.
What to watch: Attention now turns to how aggressively Boston acts as a buyer.
