You know, when I watched that video where Simon asked Andy "When are you going to let me win" and Andy said "Never", I thought, ooo-er. . . I know there is really no such thing as tempting fate, but sometimes you have to wonder.
The start of the fight-back? Andy finally converts the first of eight break points [over the match as a whole, but mostly in the fourth game of the second set] to break to 40 in the fourth game of the second set for *2-2 (no idea how long that game lasted! ).
