Hidden bagel for Lepchenko. 6-4 2-6. Haven't seen any of the 2nd set so can't really comment too much but that's a bit of a collapse.
What on earth is a hidden bagel? Never heard that before! A mini bagel yes (to denote a TB score of 7-0) but a hidden bagel...?
Katie was 2-0 up in the set, but lost it 2-6. Therefore, Lepchenko won 6 consecutive games; 6-0 in that stretch. Hence, a hidden bagel. It's 6 games without reply, but you can't see it on the finished score.
