Venus Williams scored a straight sets upset of 16th seed Veroninka Kudermetova at the ATP/WTA Cincinnati Open on Monday, bagging her first win over a top 20 player in four years. The 43-year-old American veteran, who was granted a wild card into this week's tournament, rallied superbly to polish off Kudermetova 6-4, 7-5. The seven-time Grand Slam singles champion, whose career has spanned four different decades, showed great heart to recover from 4-1 down in the opening set before overturning a 5-1 deficit in the second to seal victory.
