With an appearance at the Rio Olympics looming, Steve Johnson bounced fellow American Ryan Harrison in the Citi Open. Ivo Karlovic upset Bernard Tomic as well.
WASHINGTON (AP) — Fifth-seeded Steve Johnson ended qualifier Ryan Harrison’s season-best run in the Citi Open’s third round, winning the all-American matchup 6–4, 6–4 on Thursday.
Johnson, a member of the U.S. Olympic team headed to Rio de Janeiro next month, broke Harrison once in each set, did not face a break point himself and ended the match with a 130 mph ace.
In the quarterfinals of the hard-court tournament, Johnson will face top-seeded John Isner or No. 15 Marcos Baghdatis. Last year, Isner beat Johnson in the Citi Open semifinals.
Also Thursday, No. 13 Ivo Karlovic hit 21 aces and eliminated No. 3 Bernard Tomic 7–6 (4), 6–3.
In women’s action, third-seeded Monica Puig lost to Lauren Davis 6–4, 6–2, while fourth-seeded Kristina Mladenovic beat 2013 Wimbledon runner-up Sabine Lisicki 6–3, 6–3.
