The last match right? When at the 3rd set each player was broken several times? (each only had one hold?) Most of the rallies ended in pretty bad errors? Nicole yelling at herself to hit it in the court?
I thought the 3rd set was the most competitive, compared to the first two.
If anything, both players were fighting back, exchanging service breaks, and there were some long rallies. Winning points due to errors is expected since neither player are able to hit winners with consistency. Also, Nicole was constantly changing pace and shots on Louisa, so you're not going to see a pretty match when the balls going long or into the net, as a result.
On that play with Nicole yelling at herself, I thought it was an issue of shot selection, where she was mad at herself for going for an aggressive shot, when she should have stuck with a defensive shot to keep the ball in play.
If anything, I thought Louisa was making more errors than usual and playing less aggressively, but then again Nicole was working her backhand and grinding for those points, so she was staying in control for the most part.
