Katie Boulter moved into the third round of the Miami Open with her first career win at the WTA 1000 event after her opponent, Brenda Fruhvirtova, was forced to retire from their second-round match due to illness as Boulter led 7-6 (5), 1-0.
Despite the retirement, life was far from easy for the British No 1, who trailed Fruhvirtova 5-3 in the opening set before the Czech youngster succumbed to illness in humid conditions. Boulter will face either Beatriz Haddad Maia, the 11th seed, or Diane Parry in the next round.
