NEW YORK _ Saved by retractable roofs on its two show courts, the U.S. Open on Wednesday was able to produce a measly total of nine completed matches in the combined day/night sessions. The other 59 scheduled outside Arthur Ashe and Louis Armstrong stadiums all were rained out.
"Very happy that we have two covered stadiums now," women's No. 10 seed Madison Keys said, "and that I was scheduled in one of them. Definitely very happy about that."
Keys, the Open's 2017 runner-up and 2018 semifinalist, played in the rebuilt Armstrong, which debuted with a roof last year. And she made quick work of China's Zhu Lin, ranked 122nd, 6-4, 6-1.
