You must have been watching a delay of the match,lol. I thought Sabine took off a few playing during the match, but when her back was pushed to the wall she fought back.
When Sabine was leading 4-0 in the 2nd set tiebreaker she was involved in a rally where on two consecutive plays during the rally she failed to hit an opening on the the left side and then the right side.
I still think since it's her first match in quite awhile, Sabine stood tall. Thank You Sabine!
