Novak Djokovic vs. Philipp Kohlschreiber
Djokovic, the defending men’s singles champion, will open play on Centre Court at 8 a.m. Eastern. Djokovic, the No. 1 seed, has won 10 of his 12 previous matches against Kohlschreiber, a 35-year-old German. But Kohlschreiber beat Djokovic at the Indian Wells tournament this year. If Kohlschreiber can use his varied shot selection to find Djokovic’s weaknesses early in the match, he may have a chance before Djokovic’s physical stamina can overwhelm him in the best-of-five-set format.
