Collins was the first American women’s singles champion in Miami for six years, and with no nation better represented in the top 20 than the USA’s quintet, they will be full of belief for another home hero in Florida.

Top of the pile in 2025 is Madison Keys, the world number five who has amassed more ranking points than any player on tour, though her 16-match winning streak was ended by world no. 1 Aryna Sabalenka at Indian Wells.

Keys has won two titles this year, including her first Grand Slam at the Australian Open, and now heads to Miami in pursuit of a second WTA 1000 title.

Teenage sensation Andreeva, who claimed the last two 1000-level titles, sits ahead of world no. 2 Iga Swiatek, who is still chasing first trophy of the year, in the race to the year-end WTA Finals.

Spain’s Paula Badosa is looking to return to the top 10 after dropping out of the rank this week, while 2024 Miami runner-up Elena Rybakina could break into the top five should she go one step further and avenge last year’s defeat.
