Luis Horna to beat Victor Hanescu at 1.72-1.80 is definitely pick of the day. I just heard he picked up an injury towards the end of the Henman match so I would advise its placed at a bookie where they void it if either player retires as a precaution. If he's fit he will eat Hanescu alive though, in 3 sets.
Also taking a Grosjean single to beat Stepanek at 1.61. He seems to have found some form back at home, he likes RG and I can see him overcoming Stepanek maybe in 4 sets.
Pretty much all the rest of the matches are too low odds for my liking. Rafa will beat Gasquet but 1.25 is poor odds, and I already have enough on him outright to be excited during the match.
