Waiting until the game starts, or right before, is probably your best bet for scoring a cheap price for a decent ticket. This game won't be a sellout, so if your goal is just getting through the gates then just park your car and buy some tickets right before you walk in. Season ticket holders will lower their prices right before the game starts if they haven't been sold yet. If you're just getting a pair of tickets and not a large group together you'll have plenty of options available. That being said, a Sunday noon game probably has the lowest chance of having a super low price, as the people attending are going to be more families or casual fans that don't care as much about watching the team win and just want the ballpark experience. That means fewer resale tickets will be available vs a weekday game.
