Wozniaki vs Bartoli

Was browsing around in the markets today and couldnt believe the pre match price for Wozniaki to win in straight sets. By doing a little research you can see that over the last 20 odd matches shes only lost the first set once....so a trading opportunity was definitely possible here, I took the pre match odds for 2-0 and it ended up with a nice green, risked only small amount this time though:
