LOOKAHEAD TO TUESDAY
Serena Williams tries to move a step closer to an eighth Wimbledon title when she takes on fellow American Alison Riske in the quarterfinals. Riske upset top-ranked Ash Barty in the fourth round but will be playing in her first Grand Slam quarterfinal — in her 30th appearance — while Williams is looking for her 24th major title. With three of the top-10 seeds losing on Monday, No. 7 Simona Halep is now the highest seeded woman left in the draw. After beating teenage sensation Coco Gauff in straight sets, Halep faces Zhang Shuai of China as she tries to return to the Wimbledon semifinals for the first time since 2014. The home crowd will once again be rooting for Johanna Konta, the last British player in the tournament, who faces Barbora Strycova. Also, No. 8 Elina Svitolina faces Karolina Muchova.

TUESDAY'S FORECAST
Cloudy. High of 71 degrees Fahrenheit (22 degrees Celsius).
