I reckon Amanda was probably pretty drained from her efforts in rd1. To knock out the 4th seed (who's ranked 670) was a career best win, a great result !
From the scoreline it seems like she ran out of steam against Couchent who's unranked.
Wonder what's up with Kirsty Woolley, she was winning these types of matches in Spain last year, can't seem to buy a win atm.
