Theo Von is holding up his end of a friendly deal with Vanderbilt star Diego Pavia ... sliding into Tate McRae's DMs to lock down a date for the athlete -- so he can date his mom in return!!
The comedian has apparently been angling for an evening out with Antoinette Padilla for a while now ... as he revealed at Pavia's Vandy game on Saturday that if the Commodores upset South Carolina, the 24-year-old quarterback would have to intro the two.
Vanderbilt, of course, beat up the Gamecoks .
