Looking at the Eurosport footage of the last 3 or 4 games Mel's movement was hampered by some tight tape binding on one leg (adjusted during the match), which also probably contributed to the sharp drop in serving potency. She looked to be lacking in energy as well, having no doubt put a lot in to yesterday's recovery as well as today's in humid conditions. Very good effort to win a set though - last time they played she only won 4 games.
