Chilean third seed Cristian Garin stretched his win streak to 10 matches with two victories Sunday, including a 7-6 (7/3), 7-5 triumph over Italy's Gianluca Mager in the ATP Rio Open final. It was the second title in a row for Garin, who lifted the trophy two weeks ago at Cordoba, and the fourth of his career after the 23-year-old South American took crowns last year at Munich and Houston. Garin topped Croatian fifth seed Borna Coric 6-4, 7-5 in an early Sunday finish of their rain-halted semi-final to advance on the Brazil clay while Mager outlasted Hungarian lucky loser Attila Balazs 7-6 (7/4), 4-6, 7-6 (7/2) in the other Sunday semi finish. Giant-killer Mager upset Australian Open runner-up and 2017 Rio champion Dominic Thiem, the world number four from Austria, in the quarter-finals. Mager, a 128th-ranked qualifier playing in only his ninth career tour-level match, made the final by winning a rematch with 106th-ranked Balazs, whom he also beat in 6-0, 6-2 in the final round of qualifying. Garin, ranked a career-best 25th this week, is set to crack the top 20 on Monday. js/bb
