3-3 Mirror image of Del Potro’s last service game as this time Fed is taken to 30 but holds his nerve
2-3 After my last comment that was always on the cards – a tougher hold to 30 for the Argentine there, but he is still yet to drop his serve in this match
2-2 Another hold from the Swiss there. It just feels as though Federer is having to work that slight bit harder to win serve than his opponent is at the moment. Will that be a factor later in the set?

5-5 Del Potro with another impressive service game there. He’s in the groove and is looking the more likely winner here at the moment
5-4 Federer may have used his ‘get out of jail’ card in that game. From 40-0 it ended up as a deuce game, but he held out in the end
4-4 But Del Potro holds right back. Really hotting up now, next few games will be really interesting
4-3 Federer holds to 15
3-3 Del Potro holds again with some nice net work as we approach the business end of the set

2-2 So much for that idea! Del Potro holds comprehensively to keep it on serve at 2-2 in the second

1-1 Deuce game on Del Potro’s serve, with Federer passing up an opportunity on a break point. But Del Potro somehow holds to bring it to 1-1
1-0 Good confident start there from the Wimbledon champion, and important for him to re-establish himself a little in the early stages of the second set after the way Del Potro took the initiative to win the first

1-1 Emphatic reply from the Swiss though as he holds to love in his first service game
0-1 The Argentinian will get us underway on Centre Court. And he holds comfortably to get off the mark
Clearly a crucial one this, with the winner certain to take home an Olympic medal for their country. The loser will contest the Bronze match against the loser of Murray v Djokovic which is later today.
1st versus 9th in the world, and Federer leads the head-to-head 12-2.
