I'm liking both the underdogs to win these matches (Coria @ 2.25 and Agassi @ 1.90).
Coria has experience at the latter stage of slams unlike Ginepri...thinking Ginepri might choke a little. Coria won't make it easy for him either and Ginepri will have to play very well to win. He was also let off the hook by Gasquet who struggled with injury, otherwise he might not have progressed.
Agassi is one of the most, if not THE most, experienced players out there. Blake, like Ginepri, has never seen this far of a slam....he will have to repeat his Nadal performance to progress and, judging by his match yesterday, he seems to have slowed down somewhat and was a little lucky. Agassi seems to think his body will hold up so I expect pretty much the usual from him...which should be just about enough. Also, Blake has had such a whirlwind couple of weeks...it will eventually blow itself out.
