I think Denis has a better chance of pulling the upset simply because Felix has no experience with this level of servebot. If Isner has an off day though it's certainly possible, but I posted that Isner is one game away from nothing but tiebreaks so far, so it's gonna require Felix's best performance of the year. Denis just needs to watch Thiem's win against Roger, just stay patient and you'll get some opportunities, just make sure to cash them.
