MEMPHIS, Tenn. (AP) — Sam Querrey was upset by Alex Bogomolov Jr. of Russia 2-6, 6-4, 7-6 (7) in the opening round of the U.S. National Indoor Tennis Championships on Tuesday night.
Bogomolov saved match point in the third-set tiebreaker and won on his third match point, handing the sixth-seeded Querrey his earliest exit in eight Memphis appearances.
"Being up match points and not converting, it's easy to lose focus," Bogomolov said. "I just kept believing in myself."
Querrey, the second-highest ranked American in the world behind No. 13 John Isner, was up a break early in the third set but was undone by 33 unforced errors in the final set. Querrey won the 2010 Memphis title.
In other first-round matches, Americans Jack Sock and Ryan Harrison, former top-10 player Marcos Baghdatis and No. 8 seed Mikhail Kukushkin advanced.
Sock, who reached the quarterfinals of last year's Indoor, advanced with a 7-5, 1-6, 7-6 (5) victory over France's Adrian Mannarino. Baghdatis, the Australian Open runner-up in 2006, won his first match of the year in three tries by defeating American qualifier Rajeev Ram 6-3, 6-4.
