Well, Rublev did it!
Marc-Andrea Huesler (-3.5) to beat Kyle Edmund at 1.70 with Unibet
I really liked Edmund back in the day, but he's struggling even in Futures tournaments now, and he'll be up against a quality opponent in home conditions here, so I don't see him making much of a dent. Last week, he struggled to beat the world's no. 353 and then lost to the world's no. 1992, which tells you a lot, really.
