French Open 2017
Made £52 from the Thiem match. Staked £150 on him at 5-2 up in second set and decided to let it run into the 3rd as despite being 2 sets up, his match odds were still around 1.5 so not particularly low. Cashed out at 2-0 in 3rd. Shame I didn't let it run all the way but hey ho, no good thinking like that really.
