To use 1st Set Over Games at Match Odds market

[bureu]

Hello everyone!

Question for all Tennis Traders: Is there a way to find a connection between 1st Set Over/Under Games and Match Odds?

If I choose a match on which I would normally back Over 8,5 or 9,5 games in first set, how could it translate in Match Odds?

Under/Over markets are usually not liquid for some serious trading and 1st Set marker is really not listed enough or at all.

So, what I'm looking for is how to enter (or model a trade during games) a trade for a set that I believe it'll end Over?
