How long before game time does the twins target field open?

The gates open at Target Field 1 hour and 30 minutes before game time on Monday - Thursday games. Example: If the game is at 7:10 on any Monday - Thursday game, the gates will open at 5:40. And on weekends (Friday - Sunday) the gates open 2 hours before game time. You usually won't be able to see the Twins batting practice on week day since they start around 5, but on weekends you are there early enough to see them!
