World No. 1 Novak Djokovic moved into the third round of the Madrid Open, beating Borna Coric 6-2, 6-4 on Wednesday.
Djokovic of Serbia was out-aced 4-2 by the 19-year-old Croatian in their first meeting but controlled the run of play from the baseline. Djokovic only dropped five points on serve in the first set and closed out the win in 78 minutes with the lone service break of the second set.
Djokovic is bidding to become the first man to win 29 ATP World Tour Masters 1000 events. He is currently tied with Rafael Nadal with 28 titles.
Djokovic, the 2011 Madrid champion, improved to 17-6 at the event and will next face No. 15 seed Roberto Bautista Agut, who edged fellow Spaniard Feliciano Lopez 6-3, 5-7, 7-5.
"(It) was a satisfying performance against a young player that I had never played against, somebody who was in form," Djokovic said of Coric. "I watched his match against (Nicolas) Almagro, who won a tournament last week, and he beat him comfortably. That deserves respect.
"We know each other well. We've practice many times. I do see myself in him a little bit. We play a similar style. He's a great fighter. For his age, he's quite mature and mentally tough. We have a very nice relationship. Today was the first official match we've played against each other, so I was happy with my performance. It was a fun match to be part of."
Nick Kyrgios upset world No. 4 Stan Wawrinka 7-6 (7), 7-6 (2) to advance to the third round.
Wawrinka also never lost his serve, erasing four break points in the one-hour and 45-minute match.

The unseeded Australian then won the next three points for the win over the Swiss.
