Novak Djokovic is closing in on yet another tennis landmark, after beating Dominik Koepfer 6-3, 4-6, 6-3 to reach the ATP Rome semi-finals. The world number one is just two wins away from his 36th Masters 1000 crown, which would take him ahead of Rafael Nadal's total of 35. Djokovic will face Casper Ruud for a spot in the final following his comeback victory over Matteo Berrettini.
