Space Cowboys @ Astros tickets

Hi y’all! My family and I will be in town visiting my roots during spring break. I’m looking for tickets for the March 25th exhibition game at MMP. I’ve never been there and my son is really into baseball as well. Last home game I attended was in the dome before I moved to the east coast after college. Other than after market seat geek and the like is there another way to get tickets for the one game?

TIA!
