Nick Kyrgios took his opportunity to claim an ATP Tour title and climb the rankings during the Olympics, not so for Bernard Tomic who failed to win a match in Los Cabos, Mexico.
Tomic, who entered the tournament as the second seed, lost to world No.72 Dusan Lajovic of Serbia in his first match at the event 7-6 (7-4) 3-6 6-4.
The world No.20 Australian was on song with his own serve in the opening two sets, but failed to send down an ace in the all-important third as he went crashing out of the tournament.
Tomic opted to play in the Mexican tournament over representing Australia in the Olympics, a decision he made in May.
Tomic’s defeat comes just days after fellow-Australian Kyrgios made the most of a similarly weakened field in Atlanta to claim his second ATP Tour title.
Tomic wasn’t the only seed to fall though, fourth seeded American Sam Querrey was beaten 7-6 (7-1) 6-3 by Colombia’s Santiago Giraldo.
Spaniards Nicolas Almagro, Pablo Carreno Busta and Marcel Granollers, Croatia’s Ivo Karlovic and Frenchman Julien Benneteau all joined Lajovic and Giraldo in the quarter-finals.
