Keys Wins Again
It's been a good start to the day for the U.S. Olympic tennis team: Madison Keys has advanced to the women's semifinals, and Steve Johnson will go on the men's quarterfinals.
Keys, who is seeded No. 7, beat Daria Katsanika of Russia 6-3, 6-1.
One more victory, and Keys who's a native of Rock Island will be assured of going home with a medal.
Keys and Johnson are the last two Americans in singles play at the tennis. The other six lost early, including Venus Williams in the first round, and Serena Williams in the third.
