Jan Choinski and Jack Draper were knocked out of the first round of the Cincinnati Open on Thursday as fellow Briton Cameron Norrie progressed.<\/b><\/p>\n
Choinski bowed out after a hard-fought contest with Argentina’s Thiago Agustin Tirante, with all three sets going to a tie-break.<\/p>\n
The match lasted nearly three hours before Tirante won 7-6 (11-9) 6-7 (7-9) 7-6 (7-4) against Choinski, the world number 77.<\/p>\n
Draper led 5-2 in the second set against Martin Landaluce but the Spaniard won the next five games to clinch a 6-3 7-5 victory.<\/p>\n
British number two Norrie was broken once as he lost a tight first set before recovering to beat Croatia’s Dino Prizmic 3-6 6-1 6-4.<\/p>\n
The world number 37, who reached the semi-finals in Los Cabos<\/a> two weeks ago, edged ahead at 4-3 in the third set before setting up a second-round clash with Wimbledon runner-up Alexander Zverev.<\/p>\n Draper was playing in his first match since breaking down in tears<\/a> during his return from injury last week and he looked set to force a decider against 20-year-old Landaluce.<\/p>\n But the former world number four spurned six set points and finished with 47 unforced errors and 12 double faults against the world number 64.<\/p>\n Draper, 24, was playing just his second match since June having recently lost to Terence Atmane at the Canadian Open.<\/p>\n A persistent arm injury kept Draper sidelined and caused his world ranking to plummet from fourth to as low as 160th in a 12-month period.<\/p>\n Since injuring his shoulder at the US Open in August, Draper has struggled with bone bruising<\/a> and pulled out of scheduled comebacks at Wimbledon<\/a> and the Washington Open<\/a> this summer.<\/p>\n While he did not appear to be injured against Landaluce, he tired during the second set and his confidence seemed gone once the Spaniard made it 5-5.<\/p>\n Draper has recently consulted biomechanics expert Carlos Cano in a bid to resolve his injury problems, with the 61-year-old Mexican having already helped Arthur Fery become British number one.<\/p>\n<\/div>\n
