Arbusers

Hello,
I am curious why, unlike previous days' odds, were given generous odds today in "bottom fish" Stars' favor (penultimate) and against the very strong leader Scorchers?
Naturally, 47-runs defeat for the "Bookies' Favorite".
AFAIK, only the wicketkeeper is absent due to illness for Perth team and maybe another top player, several players recovered, but that didn't help my pre-analysis. Even their decision in the toss to bat first didn't explain the odds pre-match. The teams' power difference is huge.
Thanks.
