I really thought Tim Henman was going to go on and win when he saved those two match points.
Once he broke back, he had all the momentum and I thought he had a great chance to win.
But Dmitry Tursunov showed a lot of heart and character and he played extremely well.
And as the match progressed, Tim's movement became more sluggish and it was pretty clear that Tursunov was the fresher of the two players.
So where did it go wrong?
Henman got away from he does best. There were opportunities where I felt like he could have attacked a bit more and he hesitated.
I always thought Tim's best chance was to be aggressive.
And then it was a mental error when at 6-6 in the fifth set, 15-love, he had a pretty easy volley that he let go and the ball dropped inside the court and it's hard not to let that affect the next point or two.
I think that cost him the break and by that time - the second time it had happened - it was so deflating.
And physically, they were very hot and tough conditions.
When you're 30, you don't bounce back as easily as you do in your early 20s, and Tim had had a much tougher first-round match than Tursunov. That's what cost him in the end.
Physically his legs aren't as strong as other players' and his movement at the net becomes more of a problem because he has to make those quick reactions.
It's clear to me at this Wimbledon that he really doesn't believe he can serve-and-volley and win.

He didn't even serve-and-volley half the time on his first serve and he's got a good enough first serve to come in on.
What now for Tim? Well, each year that he plays, he's got less of a chance of winning it, so it's gone from bad to worse.
I do think because of his experience you can never totally count him out, but in these conditions it makes it even more difficult.
He'd be better off in cooler conditions where it wasn't as debilitating on his body.
There does come a time when you have to look at yourself in the mirror pretty carefully and say "What do you want to get out of this sport?"
He had his best year ever in 2004 and I think it took a lot out of him to produce the way he did. I don't think it's surprising he's struggled this year.
I also think he's the type of guy who wants to go out on his own terms, when he's playing well and winning a lot of matches.
I'd be extremely surprised if he decided to stop playing in the next year or two. I think he will for sure play the next couple of years.
