I've been very impressed with Katie Boulter from what I've seen of her. I predict her to be in the top 50 by the end of the year.

World number one Naomi Osaka has split with her coach Sascha Bajin 16 days after winning the Australian Open.

Great Britain will play Kazakhstan at home in April's Fed Cup World Group II play-offs.

 

It is the fifth time in eight years GB have reached this stage, but the first time they have been handed a home tie as they look to reach the World Group for the first time since 1993.

 

Elise Mertens has claimed the biggest title of her career by beating top seed Simona Halep to win the Qatar Open.

I watched most of that final yesterday. She came from a set and 2-0 down to win. It was a top quality match.

I have got to congratulate Novak Djokovic on winning the Laureus award tonight which is richly derserved after the great year he had last year.

World number four Petra Kvitova continued her fine start to the 2019 season by beating Hsieh Su-wei in Dubai to reach her third final of the year.

 

The 28-year-old Czech, who won the Sydney title before losing to Naomi Osaka in the Australian Open final, won 3-6 6-2 6-4 in Friday's semi-final.

 

Kvitova will play Switzerland's Belinda Bencic, who beat Ukraine's Elina Svitolina, in Saturday's final.

Britain's Dan Evans reached his first ATP Tour semi-final for over two years by beating Italian Andreas Seppi in their Delray Beach Open quarter-final.

Roger Federer has won his 100th ATP Tour title at the Dubai Tennis Championships - 6,600 days after winning his first in Milan.
