Gilles is always a slow starter, especially after a long layoff. He hasn't been playing for 5 weeks, and in fact, he said that much that he hasn't been able to do anything physically for the 3-4 weeks after Wimby. I fully expected him to be rusty and he was. I'm glad that he played in Washington, because if his first match after a long layoff is Montreal, I can be sure that he'll bomb out on that one. So I rather he just try it in a smaller tournament and get the rust out. Hopefully, he got a feel of the ball in the last match to slowly get back to the groove.
Also, this is no excuse but when he was up 4-3 in the first set, a fan had a seizure in the stands and there was a 10-15 minute break so he lost his rhythm when the match started again and lost the next three games. He had won 4 out of the last 5 games at that point so I think the set and maybe the match could have turned out differently.
