BELGRADE, Serbia (AP) — Novak Djokovic won’t defend his ATP Finals title after ruling himself out on Tuesday due to an unspecified injury. Djokovic wrote in an Instagram story, “I was really looking forward to being there, but due to ongoing injury I won’t be playing next week. Apologies to those who were planning to see me.”

Taylor Fritz followed up his runner-up finish at the U.S. Open by beating Alexander Zverev 6-3, 3-6, 7-6 (3) to advance to another big final at the ATP Finals
