Alexander Zverev signaled his anticipated arrival among the tennis elite by defeating Novak Djokovic 6-4, 6-3 Sunday to win the Italian Open. The 20-year-old Zverev became the youngest player to win a Masters 1000 event since Djokovic won in Miami a decade ago at 19. "I don't know what to say," Zverev said during the trophy presentation. "Coming in to this week I never thought I could be standing here in the finals or getting this trophy." Zverev broke in the very first game and was never really challenged by Djokovic, who appeared drained after having to win two matches Saturday to reach the final. Djokovic committed nearly twice as many unforced errors as Zverev — 27 to 14. The match lasted 1 hour, 21 minutes. Afterward, Djokovic announced that Andre Agassi will coach him at the French Open, which starts next Sunday. The title will move Zverev up to a career-high No. 10 in the rankings Monday and place him among the contenders for Roland Garros. It will also add credibility to the belief by many tennis experts that Zverev will reach No. 1 some day. "If I have only half of the career Novak has had, I'll be fine," Zverev said when asked if he can follow in Djokovic's footsteps. Tennis great Rod Laver presented Zverev with the trophy. "Getting the trophy from Mr. Laver is something very special and something I'll remember for the rest of my career," Zverev said. In the semifinals Saturday, Djokovic crushed Dominic Thiem of Austria 6-1, 6-0. Earlier, Elina Svitolina surged to No. 1 in the season-long rankings race by beating Simona Halep 4-6, 7-5, 6-1 in the women's final. It was a tour-best fourth title this year for Svitolina and the most prestigious trophy of her young career. The 22-year-old Ukrainian also leads the tour with 31 match wins this season. "Every day I'm just trying to work on my mental part, my physical, my tennis," Svitolina said. "Everything just came together and I'm very happy that it's happened in such a big tournament." The fourth-ranked Halep was in full control and serving for the first set at 5-2 when she rolled her right ankle while sliding over what appeared to be a small hole in the Foro Italico stadium court. While Halep was able to eventually win the opening set, she required treatment to her ankle from a trainer twice and was late getting to shots as the match wore on. "Sorry guys for third set," Halep told the crowd. "It was a little tough for me to get through but Elina played great." Halep was playing in her second clay-court final in two weeks after winning the title in Madrid last Sunday. Svitolina also required medical treatment from a trainer midway through the second set, for an apparent problem with her left leg. — AP
