ATP roundup: Terence Atmane upsets Frances Tiafoe in Washington

France's Terence Atmane avenged a first-round Wimbledon loss to Frances Tiafoe, prevailing 4-6, 6-3, 6-4 on Monday in the first round of the Mubadala DC Open in Washington.

Tiafoe, a Washington-area native, was the tournament's sixth seed.

Atmane got the decisive service break in the next-to-last game, then served out the match.

Earlier in the day, third-seeded Taylor Fritz swept his service games and rolled to a 6-3, 6-4 win over Belgium's Zizou Bergs.

Fritz saved all four break points he faced while converting two of his four break opportunities. The California native was playing his first match since losing in the quarterfinals at Wimbledon to Germany's Alexander Zverev.

Fourth-seeded Lorenzo Musetti won an all-Italian matchup when Matteo Arnaldi retired while trailing 6-0, 3-1. Musetti was returning from injury issues that kept him out since early May.

Also advancing to the second round were Australia's Aleksandar Vukic, Japan's Kei Nishikori and Chile's Alejandro Tabilo.

Hernandez, a 27-year-old qualifier who is ranked No. 498 in the world, held serve while trailing 5-0 in the first set to avoid a double bagel. Tomic, a 33-year-old who is ranked 171st, made the main draw as a lucky loser from qualifying.

In other first-round action, U.S. qualifier Tristan Boyer downed Canada's Gabriel Diallo 7-5, 6-2. The night slate included fifth-seeded Cameron Norrie of the United Kingdom facing Aleksandar Kovacevic, and Hong Kong's Chak Lam Coleman Wong opposing Darwin Blanch.
