Washington, DC (Tennisfiles) – Second seed Sam Stosur of Australia kicked off Tuesday’s action at the 2015 Citi Open with a convincing 6-2 6-2 win against Kristina Mladenovic of France.

British qualifier Naomi Broady had one of the tightest matches of the day, upsetting higher ranked Jarmila Gajdosova of Australia 3-6 7-5 7-6(6) in 2:17. She gave Mehrban her thoughts on the match, her warm-up routine, and her favorite pre-match meal in a very enjoyable post-match interview:
