I suspect that if either of Tara or Sam had won, Naomi would have probably had more motivation to put up more of a fight. Naomi's was the last match. She has had an outstanding few weeks, has played tons of tennis thousands of miles from home, picked up tons of ranking points, and was probably somewhat fatigued. As she was last on court, knowing her friends had already lost and were probably packing their bags for the airport to come home........the prospect of giving 110% to stay on alone in Japan probably wasnt a massive motivator. Her trip's objectives have been more than achieved.
