Middle Tennessean Last American Man In Tennis' Australian Open

MELBOURNE, Australia -- Gallatin's Tennys Sandgren scored a grueling five-set upset victory over No. 5 seed Dominic Thiem Monday in the fourth round of the Australian Open to advance to the quarterfinals. Sandgren, who played collegiately at the University of Tennessee, is the only remaining American in the men's draw after his 6-2, 4-6, 7-6 (7-4), 6-7 (7-9), 6-3 win Monday.

Sandgren, 26, had never won a match in a Grand Slam until this year. He's now won four, including two wins against Top 10 seeds: he defeated No. 9 seed Stan Wawrinka in the second round before Monday's upset of Thiem.

Sandgren will square off with 21-year-old Hyung Chung of South Korea in the quarters. Chung scored a shocking upset himself Monday, beating six-time Australian Open champion Novak Djokovic in straight sets.

Despite playing tennis, being born and raised in Tennessee and playing for the Vols, Tennys Sandgren is named for his grandfather, who was not from Tennessee and didn't play tennis, making Sandgren's aptonymous first name merely coincidental.
