American Chris Eubanks kept his shock Wimbledon run alive Saturday as he took down Aussie Christopher O'Connell in straight sets, winning 7-6(5), 7-6(3), 7-6(2)

Eubanks, who is playing in the main draw at Wimbledon for the first time, fired 23 aces past his opponent to move onto the fourth round in London.

It's the first Grand Slam Round of 16 of the 27-year-old's career, and up next is a tough test vs. world No. 5 Stefanos Tsitsipas.

Prior to this year, Eubanks had never even been ranked in the top 100 and even became a part-time commentator on the Tennis Channel as he mulled his future in the sport, according to the Wall Street Journal.

But things have gone his way this summer.

He won his first ATP title earlier this month at the Mallorca Open, and now has a live ranking of No. 38 in the world after his latest victory over O'Connell.

Eubanks beat Brazilian Thiago Monteiro and British No. 1 Cam Norrie to set up his third-round matchup.

He's now one of just four Americans left in the tournament, with Frances Tiafoe and Madison Keys competing Saturday.

Jessica Pegula will face Ukrainian Lesia Tsurenko on Sunday.
