Add another teenager to the growing ranks of young #NextGen stars on the rise. German Daniel Altmaier, displaying a complete all-court game and Richard Gasquet-like backhand, convincingly defeated Brit Jonny O’Mara 7-5, 6-3 in the final of the Qatar F4 Futures at Doha Saturday afternoon. The 18-year-old German won his third title in five finals this year, and improved to 60-24 in 2016, all on the Futures circuit. Altmaier, a model of consistency, has also reached the semifinals twice and the quarterfinals nine times in his 27 tournaments this season. The No. 448-ranked youngster served 15 aces, won 86 percent of his first service points, didn’t commit a double fault and saved three of three break points on the afternoon. At 6-foot-2 and 174 pounds, Altmaier reminds one of a younger Dominic Thiem, both in physical stature and game. One can certainly see potential for a great future for the youngster. The German breezed through his first three service games, winning all 12 points. O’Mara, 21 and ranked No. 544, held his own most of the first set, saving a break point in the third game and then forcing three break point opportunities on Altmaier’s serve in the eighth. The German erased the breakers with strong serving and broke through in the 11th game to lead 6-5. Altmaier served an ace on his first set point to take the opener. Swinging freely and pounding his backhand crosscourt and down the line for winners, Altmaier was in complete command in the second set. He parlayed service breaks in the seventh and ninth games to take the match in one hour and 23 minutes. O’Mara had knocked off top seed Ramkumar Ramanathan in the quarterfinals.
