Looking at our matchup, we have Irene Burillo, unseeded player who has been going neck and neck with her opponents, winning twice against Ristic M. and Pieri T. However, her losses are not ones to ignore, all of them in straight sets, not a pretty sight. It's fair game to say she's inconsistent with a capital 'I'.
On the other hand, we've got Nuria Parrizas Diaz, our 4th seed. Now, it's evident Diaz has a tendency to go down as well, but interestingly when she does win, she takes it home in love sets. If that's not a show of power, I don't know what is!
Considering all the huff and puff, it seems clear to me folks that Nuria Parrizas Diaz, as the favored player, has a better chance of bouncing the ball onto the victory court. Afterall, there's a reason why she's seeded 4th.
Albert’s Prediction: Parrizas Diaz in 3 sets.
