If you have something in the bag, it means that you are sure that you will achieve it or acquire it. We usually use this expression to predict a future success that seems certain or, at least, highly probable.
This expression can be used in a variety of situations, although it is better suited to informal contexts. For example:
- Team A is leading the game by 8 points, so I think it’s safe to say they have this victory in the bag.
- I have a third interview for the Fundraising Manager position tomorrow, but I’m pretty sure I have it in the bag already. The HR team seemed really enthusiastic after my last interview.
A. Good luck on your presentation this afternoon!
B. Thanks. I have to admit that I’m a bit nervous to present in front of such a large group.
A. Don’t be! You got this in the bag!
Did you know? Apparently, this phrase originated in the early 1900s based on a superstitious belief of the New York Giants, an American baseball team. When the Giants were in the lead during a game, they would carry the ball bag off the field because they believed that the game was, symbolically, in the bag with the baseballs. They thought that if they carried the game off the field, it would mean that they couldn’t lose.
