Any week there are three tournaments on in the same seven days, we always manage to end up with a wide range of weird and wonderful results.

This week was as weird and as wonderful as they come.

With three completely different champions from three different parts of the top 100, there is plenty of tennis to dissect.

Dominic Theim has arrived, and he means business

Ever since he won his first title in his native Austria at age 20, everyone knew Dominic Thiem was top-20 bound at the least.

This week, on the way to his fourth ATP title in Buenos Aires, the youngest man in the world top 20 dismissed two former champions at the event –  Rafael Nadal in the semi-final and Nicolas Almagro in the final.

The Austrian star is slowly rising. How far it will rise this year is the question. At the start of the year I had him tagged as a possible end-of-year top-15. If he continues playing like this, that may not be far enough.

Taylor Fritz – the future of USA tennis

As disrespectful as some may think I’m being to Jack Sock, even the man himself could hardly deny how good Taylor Fritz is going to be and how much better he is likely to be than his countryman.

He only turned 18 five months ago, yet he just last week went to his first ATP Final. Even better, it was on US soil in Memphis, Tennessee,

The teenager played valiantly against world No.6 Kei Nishikori, losing 6-4, 6-4 in the Final. Jumping all the way to world No.102. It’s safe to say that Fritz will be feared be almost anyone who is drawn against him in the first round of a Slam.

Aussie watch: John Millman is slowly making his way up the ladder

This year has so far been a good one for John Millman – the best in his career. The past two weeks he has been slowly climbing up the rankings to his spot now at 59.

He may not have any titles or finals this year, but the past two weeks he has been to the quarter-finals and round of 16 – and maybe should have gone further this week.

This week he is in Delray Beach along with a number of other Australians, and has drawn American Steve Johnson in the first round. If he serves well and keeps down the unforced errors, this is a match he can win.

Is Martin Klizan here to stay; take four

Since turning pro in 2007, Martin Klizan has had more than his fair shire of false dawns, to the dismay of Slovakian tennis fans.

He has been as high as 24, and after his biggest title so far in Rotterdam this week, he sits at No.25 in the world.

With three other career titles, including finals wins over Fabio Fognini and Gael Monfils, no-one quite knows what to make of Martin Klizan. Is he destined for greater things? Or is he another man just passing by the top-30?

Is Nicolas Almagaro back?

After multiple quarter-final appearances at the Aussie and French Opens, and a career-high of world No.9, most thought the top-five would be well within reach for Spanish baseliner Nicolas Almagro.

A number of persistent foot and back injuries later, and Almagro sits outside the top 50. However, after an impressive week in Argentina, we have seen signs that Almagro might be on his way back.

It’s unlikely now that at age 30 he’ll summit the heights he was expected to, but let’s hope for his own personal sake that he can get back to winning titles – he won five in his career best year in 2011.

Best of luck in Rio de Janeiro this week, Nic.
