Watch: Serena training in Croatia

Serena Williams is back on court training, but she's not in one of her typical training bases in Los Angeles, Florida or Paris. According to Croatian newspaper Glas Istre, she's in Croatia training with her hitting partner SaschaBajin. Was the shorter hair an attempt to go incognito?

It's good to see Serena back on court after the last two weeks. After suffering a third-round loss to Alize Cornet at Wimbledon, Williams retired from her doubles match after a worrying display of dizziness and lack of coordination, which she blamed on a viral illness.

Williams was scheduled to play this week's tournament in Bastad, Sweden but withdrew due to illness. Her next tournament is the Bank of the West Classic in Stanford, California, which begins on July 28th.
