Cameron Norrie has booked his place in the main draw of the Miami Masters with a three-set victory over Patrick Kypson.

The British number three is looking to break into the world's top 100 ahead of the French Open and Wimbledon, and the left-hander has taken another step towards that target by beating the American wildcard.

Kypson claimed the opener on a tie-break, but Norrie rallied to register a 6-7 6-3 6-1 triumph to secure a spot in the main draw of a Masters Series event for the second time this month.

Compatriot Liam Broady joins Norrie in earning a spot in the first round courtesy of a 6-4 7-6 triumph over Canada's Filip Peliwo, with Broady saving a set point in the second set before prevailing 7-2 in a tie-break.

In the women's draw, Katie Boulter has made full use of her wildcard into qualifying by overcoming Carol Zhao by a 3-6 7-6 6-2 scoreline.

Boulter - the British number five - lost her opening two service games but the 21-year-old battled back to come through a second-set tie-break before dominating the final set against a player who sits 69 places above her in the world rankings.

Earlier on Tuesday, Heather Watson suffered a first-round defeat to Brazil's Beatriz Haddad Maia.
