Medvedev v Alcaraz
Tim Henman
Former British number one on BBC TV
I don't think Medvedev does a lot of adapting. He has a style of play which is very effective and he likes to return deep into the court - he is a little reactive than proactive.
He hits it very flat and hits it through the court - that is where Medvedev backs himself.

Hewett is a set and a break behind, a long way back now for the Briton.
