Petra Kvitova is now on a 13 match winning streak. After losing 10/8 to Andrea Petkovic in the decider at the Australian Open last month she has gone on a surge. The title in St.Petersburg was followed by a couple of Fed Cup singles victories and now the title in Doha, Qatar. Unlike in Russia where she did all the front-running, she showed a lot of bottle coming from behind last week. A set down to Radwanska, Wozniacki (semi-final) and then Muguruza in the final, no mean feat, she found her game when she needed it most. The Czech also took care of Elina Svitolina on the way. Simona Halep pulled out before the semi-final against Garbine Muguruza, the right ankle still seems to be a problem. CiCi Bellis made the last eight beating Kasatkina, Keys and Pliskova on the way.

Roger Federer had a few tests in Rotterdam, against Kohlschreiber, Haase (where he dropped his only set of the week) and Andreas Seppi, but these are players Federer has a very good head to head against (13-0, 3-0 and now 14-1 respectively). His sole defeat came against Seppi in the Australian Open 2015. These are very good matchups for him and ‘The Fed-Express’ then beat Dimitrov for the seventh time in a row in the final 6/2 6/2, he still hasn’t lost to ‘Baby Fed’. There were rumours of Dimitrov feeling sick before the final but the Bulgarian didn’t use it as an excuse. Sascha Zverev lost out to Seppi in round two and fourth seed David Goffin pulled out of his semi with Dimitrov a set down. The Belgian taking one in the eye, after the ball deflected off his racket in a freak incident. Federer’s win this week sees him go back to one in the rankings.

Kevin Anderson beat Sam Querrey in the final of a new event in New York, this was the top seeds going head to head. The South African seems to love NYC. He got through a tough match in every round, going the distance each time. Wins Over Escobedo, Tiafoe, Nishikori and Querrey. Great to see Tiafoe make the last eight here, I really want to see this lad kick-on.

Dominic Thiem had no worries as he ripped through the field in Buenos Aires without dropping a set. The top seed was tested in the quarter-finals by Guido Pella, who continues to impress me at this level and then the Austrian dispatched Gael Monfils and Aljaz Bedene, comfortably to land the title. Thiem said the conditions were very much to his liking here especially when its hot and the ball is bouncing high, he loves the clay and as good as some players were in this field, he is cut above when playing at this level. The favourite in the bottom half was Diego Schwartzman, playing in front of his home crowd but Aljaz Bedene beat him in straights in the quarter’s having already beaten third seed Albert Ramos-Vinolas. Second seed Pablo Carreno Busta once again lost his opening match, to Guillermo Garcia-Lopez this time.
