Catching a game while in town for business, where to park?

Hey everyone, will be in Houston for a work trip and plan on catching the game on Monday 4/17. Ill me coming down from IAH (hotel/work is NW of the city near Sam Houston race park). Is there a preferred lot that isn't crazy expensive but not too far of a walk from the stadium? I don't mind a 5-10min walk if needed. Thanks!
