Fifth seed Stan Wawrinka was knocked out by Daniil Medvedev in the biggest shock on day one of Wimbledon 2017.
The 32‑year‑old, a three‑time Grand Slam champion, needed ice on a knee injury between points as he fell 6‑4 3‑6 6‑4 6‑1.
Earlier, Rafael Nadal began his bid for a third Wimbledon title with a comfortable win over John Millman.
