A lot of delays at the French Open in the opening two days and if this keeps up, there's going to be a congested schedule down the line that could lead to an upset. So, on today's calendar, there's only one obvious match between a top player and an unseeded one and that's the game with Khachenov.
The odds aren't great but if all the favorites go through, that's like a 1.35 parlay on the top seeds not getting knocked out in the first round. Decent stuff although it's only available 4 times a year.
