Britain’s Cameron Norrie progressed to the third round of the Barcelona Open after a gritty 6-3 4-6 6-4 win over Ethan Quinn.
Norrie, 30, was given a stern workout by the 22-year-old American during a two-and-a-half-hour contest at the Real Club de Tenis Barcelona.
The British number one broke Quinn’s serve in the fourth game to go 3-1 up and then saved a break point in the ninth game to clinch the first set.
Norrie recovered from break in the second set to trail Quinn 5-4 but then could not hold serve to even things as his opponent, ranked 50th in world, closed out the next game.
Left-hander Norrie secured an early break in the third set and held his nerve to seal victory despite a spirited effort from Quinn.
Norrie, who is seeded seventh, will play Spain’s Rafael Jodar in the quarter-finals.
Elsewhere, Katie Boulter clinched a 7-6 (7-5) 4-6 6-1 victory over Jaqueline Cristian of Romania to reach the last eight of the Open de Rouen.
Boulter, 29, had won a tense first set via tie-break before third seed Cristian battled back to square the match in a gruelling second set.
However, the British number three broke Cristian’s serve in the fourth game of the final set to go 3-1 before she ruthlessly dispatched her opponent.
At the Stuttgart Open, Iga Swiatek cruised to a straight-sets victory over Laura Siegemund in her opening match of the clay-court season and first under new coach Francisco Roig.
The former world number one, whose previous outing was a surprise early exit at the hands of compatriot Magda Linette at the Miami Open last month, beat Siegemund 6-2 6-3 to progress to the quarter-finals.
