Sevastova was so mentally tough when it counted. Saved a match point at 4-5, 2 at 5-6 and another 2 at 8-9. Mertens fell over at least 5 times during the final set, including twice at 6-6. Very entertaining match! Sevastova was just a bit braver towards the end and had a bit more ability to open the court up, it will be devastating for Elise.
