Match prediction: Erjavec in 3 sets.
Update: There were rain delays in Colina and this match was delayed by almost 3 hours. Rain delays can change matches as the players are hanging around not knowing when they will actually get on to the court.
Erjavec served first and went 15-40 behind. Her price went to 1.68 which was a little too low to enter. I waited for the break. She recovered to hold serve. The next 2 games were holds to 30.
Monnet served at 1-2 and was broken to 30. I was expecting a close match so I laid Erjavec at 1.27. Erjavec had not looked comfortable on serve.
In the next game, Erjavec again struggled on serve and faced a break point. Her price went to 1.38. I could have removed some of the liability but I wanted a better price so I waited. Erjavec recovered to hold. The next game was an easy hold for Monnet. Erjavec continued to have problems on serve and in the next game, she faced another break point. She was likely to be broken eventually, so I waited. This time, Monnet got the break. I removed almost all the liability at 1.52.
So at this point, I had my profit on Erjavec with a small red on Monnet. Monnet was serving slightly better and had only faced 1 break point. Erjavec had faced 4 break points. Monnet served at 3-4 and had her worst service game of the set. She saved 3 break points but was broken on the 4th to trail 3-5.
I certainly didn’t trust Erjavec to serve out the set so I hedged evenly at 1.30. The market also didn’t seem to trust her! Erjavec faced 4 break points when serving for the set but somehow managed to hold.
Monnet served first in set 2. I waited for her to have her service game before laying Erjavec. Monnet was broken to 15. I laid Erjavec at 1.13.
Erjavec was taken to deuce in the next game but held serve to lead 2-0. In the next game, Monnet was broken again. Erjavec’s price was 1.04. She was having a terrible day on serve. The profit from the first set meant that when I laid Erjavec, I had zero liability I felt that I had to add to the lay at 1.04. Second sets can be very different to the first set but I wasn’t sure she could suddenly start serving well. I added to my lay of Erjavec at 1.04 leaving a small(ish) liability. If Erjavec ran away with the set, there would be nothing I could do to save any of the loss so I had to be prepared to lose the liability I had on Erjavec.
Just as I placed my lay, Monnet called for a medical time out. Great! When the match continued, Erjavec was broken to 0! Monnet then held serve easily. I removed my liability at 1.23. I left the large green on Monnet. In the next game, Erjavec went 15-40 behind. I backed Erjavec at 1.51 to move some of the profit to her but left the much larger profit on Monnet. Erjavec saved the 2 break points but had another which she did take. 3-3!
Another easy hold for Monnet gave her a 4-3 lead. Both players had poor stats in the set but Erjavec’s were awful. In the next game, Erjavec was broken for the 3rd time in a row. Broken to 0. I hedged evenly at 1.70 on Monnet’s ladder (around 2.40 on Erjavec’s ladder).
Monnet was broken serving for the set but Erjavec was then broken for the 4th time in a row to give Monnet the set. I did not get involved in the 3rd set but Erjavec held to 0 in her first service game and was broken in her 3 other service games!.
Monnet won 3-6, 6-4, 6-2.
The graphs below show how the players’ stats changed during the match. You can see the decline in Erjavec’s 1st serve points won and 2nd serve points won percentages. It was her 2nd serve that just about held her together in that first set.
