Didn't see the match, just watched the 1st set scoreboard tick over.
Swan, initially 1-3 down, but broke Errani and squared it at 3-3. Then at 5-5, made the decisive break, and closed out the following service game. It was great to hear a couple of hours later, that the second set was also won with the same scoreline.
7-5, 7-5 is the best result, isn't it? Swan gave herself 15 break point chances, and took 6 of them. Swan has always been able to break the opponents serve. The return game is excellent, especially against the 1st serve.
Though Errani was the seeded player, I think she would have been the one thinking the draw was unkind. It's just the first match though, and it's point by point all the way.
