(Reuters) -Coco Gauff lost to unseeded Magda Linette 6-4 6-4 on Monday as she missed out on a place in the Miami Open quarter-finals after a tough day for Americans as holder Danielle Collins, Amanda Anisimova and Ashlyn Krueger also went out in straight sets.
Gauff, seeded third, struggled mightily with her serve, committing 12 double faults and putting just half of her first serves into play while unforced errors piled up against her 34th-ranked Polish opponent.
