Marin Cilic has upped his record over Donald Young to an unblemished 4-0, with the highest seed left in contention at the Queen's Club grass event defeating the American 6-4, 7-5 to reach the semi-finals.
Rain, after a week of excellent weather, finally arrived to play its part in disrupting play at the Aegon Championships at Queen's but didn't prevent the singles semi-finals from being completed leaving Marin Cilic and Fernando Lopez to contest the title match on Sunday.
There were no breaks in the second set although Muller had to fend off two set points at 5-6, the first after turning around a rally Querrey had been in control of with a crafty lob and the second with an unreturnable serve.
"I have wanted to win this tournament so bad", said No. 32-ranked Lopez, who expressed delight that Cilic was playing in a semifinal of the doubles on Saturday evening.
'You know, Roger didn't play much, so it's tough to know his form, ' Cilic said.
With neither player letting their serve falter, it took a tie-break to decide the champion and Cilic's fears came true.
Instead, one lapse of concentration at 5-6 blotted provided the veteran from Luxembourg to snatch the second set and level.
"I was never top 30 before in my life, and now this year for the first time I have a "2" in front of my ranking. I knew it would be hard today but I've played some of my best tennis all week".
The Croatian won 93 per cent of points on his first serve, driving Lopez into the backcourt. "I played really well throughout and Gilles was pushing me to the limits", Cilic said.
"It is true that I'm going into Wimbledon with a lot of confidence".
"Wow, I can not believe I have finally won this trophy", Lopez said.
Dimitrov closed out the set on the resumption to level the match but it was Lopez who finished the stronger into the evening as he opened up a 4-2 lead before securing victory in just over two hours on court when the sixth-seeded Bulgarian's return dropped long. It is one of the tournaments that you, first of all, you love.
"I thought that at the end of the tiebreak after losing match points I wouldn't make it but I managed to do it".
