Andy beat Granollers then went out to Gulbis last year, see playing activity, 2013 at http://www.atpworldtour.com/Tennis/Players/Top-Players/Andy-Murray.aspx?
He also played doubles with Colin and reached the finals. He was asked about doubles this year
Q. You talked about getting plenty of matches in before the US Open. Last year you had a really good run here in the doubles. Were you tempted to use that again to sort of build up your match sharpness or did it just not work logically?
ANDY MURRAY: No, I wasn't originally going to have a bye in the tournament because I would have been‑‑ before Rafa pulled out, I was told I was going to be playing on Monday evening a little while ago.
So I planned all of my training and everything around playing my first match on Monday evening and, you know, arranged to come here on Thursday to get here a little bit earlier to get used to the conditions.
Yeah, I had been asked by a couple of the guys‑‑ Colin had asked me to play doubles, and I said to him, Sorry, but I'm not going to have a bye so I don't want to play.
Then, yeah, obviously I found out Wednesday afternoon/evening when Rafa pulled out, so I had thought about it, but not this year. http://www.asapsports.com/show_interview.php?id=101548
Oh dear. That's a shame because I enjoyed watching Andy and Colin play last year. Also it would have given Andy more match practice.
