They make it more likely that the Uruguayan's first three-point haul comes when the Black Cats play host to North East rivals Newcastle eight days later.
That is priced at 15/8 with 11/2 chalked up about the first win coming at Hull in their following match.
Poyet has signed a two-year deal but is just 7/4 to leave his post by the end of the current season. He is 2/5 to still be in charge for the club's final game of the season.
