Round-up: Jelena Ostapenko shocks Carla Suarez Navarro
Jelena Ostapenko secured the first major upset of Wimbledon as she ousted Carla Suarez Navarro 6-2 6-0.
Ostapenko, the 2014 junior champion, took less than an hour to dispatch ninth-seeded Suarez Navarro and will now face Kristina Mladenovic in round two.
The Latvian claimed three breaks of serve to secure the first set before not conceding a game to the Spaniard in the second set.
French Open runner-up Lucie Safarova beat Alison Riske 3-6, 7-5, 6-3. Safarova, the sixth seed at SW19, was dumped out of Eastbourne in the first round and was one game away from suffering the same fate at Wimbledon.
However, at a set and 5-3 down the Czech rallied to secure the comeback win. Heather Watson was level at one set each when bad light brought an end to her encounter with Caroline Garcia.
Elsewhere, 2013 quarter-finalist Sloane Stephens overcame Barbora Strycova 6-4 6-2 to move into the next round.
