I never heard they void it if a player does not start, usually it is voided only if he does not play at all. Anyway - Foden scored in OT so it would be a lost ticket.

I did hunt surprises yesterday, I was close to one with Fognini. Also had Duckworth against Aliassime, both of them on insane odds after they went a set down.
Didn't bet against Medvedev which passed, against City which passed, but the worst miss was not betting against Rune when he wet a set up - missed that because I was in a hurry. Jarry won of course.

So, bottom line, close but no cigar. But this is my type of betting so I'll hit a few soon enough.
