. . .and holds, 6-1 7-5

Typical loss of focus sees him throw the third set away with another double fault - this time on set point. That having battled from 1-4 down to 4-4, break point.

He has a serious issue with double faulting when down break point.

Into a fourth...

Double break up, *4-1

And hands one of them back 

Has break points to regain the double break... which he does.

Serving for the match then. Now would be a good time to re-discover that first serve.

6-1 7-5 4-6 6-2. Good lad. But it should have been done in 3 really.
