The team announced Monday that it has moved up the date of the Grammy Award-winning singer's show in Houston from Oct. 13 to Sept. 9.
Houston, which hasn't been to the postseason since 2005, wasn't expected to contend entering this season. But the Astros got off to a great start and entered Monday just one game back in the American League West and in first place for a wild-card spot.
In the announcement, the Astros said that they made the change as they "proactively prepare for potential postseason play."
Tickets purchased for the October show will be honored on Sept. 9, but those who are unable to attend because of the change can receive a refund from Ticketmaster.
Swift had been scheduled to perform in Fargo, North Dakota, on Sept. 9. That show will now be held in October.
