Hello, i was looking at odds for tennis match Montanes/Giraldo today in Oeiras and i was very surprised to see Montanes is the favourite and Giraldo outsider (odd about 2.1). All criteria tell Giraldo should win (i'm not saying he's gonna win, one never knows in sport, but criteria say he should be the favourite of bookmakers in odds):
-in head to head Giraldo leads 4-1 (and he won the two last matchs vs Montanes this year in straight sets)
-the shape of the moment is in favour of Giraldo too (ok he was distroyed by Nishikori in final of Barcelona, but he has made however great tournament with big wins)
-at ATP ranking Giraldo is in front of Montanes
...
Once more, i'm not saying Giraldo is going to win, i have no idea about it, but i would like to understand how is it Montanes is the favourite? Are there criteria i ignore?
