Muller in semis of Queen's club tennis meet

A pair of former champions each took a step closer to possible repeat titles at the Queen's club pre-Wimbledon event on Thursday, with fourth seed Marin Cilic and Sam Querrey both advancing.

In the doubles, Jamie Murray and Bruno Soares made the semi-finals, beating Michael Venus and Ryan Harrison 7-6 (7/1) 4-6 10-6.

"Mr Nice Guy" Marin Cilic believes a more aggressive attitude on court can propel him towards a title push at Wimbledon.

The 35-year-old, who suffered a heartbreaking defeat in the 2014 final when he held a match point against Bulgarian Grigor Dimitrov, this time saved one in a tense tiebreak shootout before toppling the Croat after two hours 32 minutes.

However, Muller committed another unforced error handing Querrey the mini-break advantage back, and the 2010 champion was in a good position to claim the second set by taking a 5-3 lead.

"It was not easy to keep calm after not converting a lot of break points I had in that second set and then losing it, and then also, beginning of the third I had love-40 and lost that game, but eventually I got the break and really played a great match".

Cilic became the first player to break Muller in the tournament despite a barrage of 22 aces from the world number 26 and hammered down 20 aces of his own to return to the Queen's final for the first time since 2013. Amazingly, Muller took it at the first time of asking with a forehand stretch volley victor, winning his seventh successive match in the process.

"But to be able to win two matches in a row gives me more confidence than winning the tournament seven years ago". Cilic is 1-1 in final appearances on grass.

"Today's match was a really high level", said the world number seven who is coached by former grasscourt specialist Jonas Bjorkman.

"I played him here past year and had a match point".

"I've felt really good on serve all week".

With neither player letting their serve falter, it took a tie-break to decide the champion and Cilic's fears came true. He's very aggressive, standing inside the baseline. Right at the beginning of the match he was fist pumping.

Swiss great Roger Federer thrashed Alexander Zverev to win his ninth title at the Wimbledon warm-up tournament in Halle on Sunday. "I was waiting so long so I'm so happy today".

He's managing the points and games so well, and the fight he showed there, the way he upped his service percentage in the third set when he must have been exhausted.

Lopez is expecting another stern test against Cilic.
