Seven‑time Wimbledon champion Serena Williams recovered from being a set down to beat teenage qualifier Kaja Juvan and reach the third round.
Williams was surprised by the 18‑year‑old world number 133 who twice broke serve to win the first set.
The 11th seed, 37, responded to take control in the second and eventually closed out the decider for a 2‑6 6‑2 6‑4 victory in one hour 36 minutes.
Williams says she played well and she started out a little slow.
