Top seed Richard Gasquet withstood a barrage of bombs from big-serving Sam Groth last night to edge the Australian 7-6 (3), 7-6 (5) in a second-round encounter at the Claro Open Colombia in Bogota. Gasquet, playing his first match since squandering nine match points in a second-round loss to Nick Kyrgios at Wimbledon, improved to 20-11 on the year. Groth was fresh off reaching his first ATP Tour semifinal last week at Newport, which boosted his ranking to a career-best No. 99 in the world on Monday. There were no breaks of serve in the 1-hour and 44-minute contest, with the No. 14-ranked Gasquet never facing a break point and Groth saving all five of his. Groth served 20 aces, while Gasquet had 12. “I stayed strong mentally and I think it was the key of the match,” Gasquet said. “I played a good match because he’s a tough opponent, especially here in Bogota.” Bogota sits at 8,646 feet and the ball flies at a faster pace and bounces higher at altitude. Not exactly what you want when you’re playing a guy who serves as big as Groth. The Aussie won 16 of 17 first service points in the first set, but Gasquet scored three mini-breaks to just one for Groth in the tiebreaker to take it 7-3. Gasquet started to read Groth’s serve a little bit better in the second set, but still couldn’t break the Australian. Groth saved two break points in the seventh game and three in the 11th, before double-faulting at 5-6 in the tiebreaker. Gasquet won 56 of 71 points on his serve, Groth 57 of 78. Gasquet will meet eighth-seeded Victor Estrella Burgos in a quarterfinal matchup tonight.
