MELBOURNE, Australia (AP) — Novak Djokovic has put aside problems with his left hamstring and a persistent heckler to beat 191st-ranked French qualifier Enzo Couacaud 6-1, 6-7 (5), 6-2, 6-0 in the second round of the Australian Open. Djokovic is seeking a 10th trophy at Melbourne Park and a 22nd Grand Slam title overall. He took the court knowing that No. 1 seed Rafael Nadal and No. 2 seed Casper Ruud already were out of the tournament.
