The season got off to a bad start for the Roadrunners as they conceded five goals in the first half in a formidable Baylor performance that showed why they are ranked 12th in the country.
It took Baylor just three minutes to open the scoring as Vic Hoffman received Bri Campos' pass on the right and was able to chip freshman keeper Katherine Tesno.
In the eighth minute Baylor doubled their lead as Hoffman looked to score again but this time Tesno saved well only for Ashley York to tap home the rebound.
UTSA did manage to have a corner in the 15th minute but it was only temporary respite as another rebound saw Kat Luclow make it three for the Bears.
Soon enough Baylor made it four after a poor pass allowed Alex Klein to take possession and find Natalie Huggins in the box allowing her to score the fourth of the night.
UTSA did manage to get back in to a tight midfield contest but that was only temporary respite as Balyor made it five in the 35th minute with Campos putting away Justine Hovden's cross for the fifth before half-time.
The Second half saw both teams rotating their squads regularly to try and give everyone some game time and start deciding their ideal XI before they get in to conference play.
Baylor were content to just keep possession and hold UTSA back during the second half although UTSA did have some more chances with Laylla Da Cruz finishing with four shots for the Roadrunners.
