MELBOURNE, Australia (AP) — Learner Tien, a 19-year-old qualifier from California, became the youngest American man to reach the Australian Open's third round since Pete Sampras in 1990, upsetting a racket-tossing Daniil Medvedev 6-3, 7-6 (4), 6-7 (8), 1-6, 7-6 (10-7) in a match that began Thursday night and ended in the wee hours of Friday.
The 4-hour, 49-minute contest had a bit of everything, including — hard to believe — a six-minute rain delay that interrupted play shortly before 2:30 a.m. with Tien serving at 5-all, 15-all in the fifth set. When they resumed, Medvedev broke and served for the victory at 6-5, but Tien wouldn’t cede a thing. He immediately broke back to force the concluding first-to-10 tiebreaker that he emerged to win shortly before 3 a.m., about two hours after he failed to convert his initial match point.
