HOUSTON -- The Houston Astros have shaken off Taylor Swift's original tour date at Minute Maid Park in case of a playoff run.

The Astros announced on Monday that they'd 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 post-season since 2005, wasn't expected to contend entering this season.

But the Astros got off to a great start and entered Monday's games 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 post-season play."

Tickets purchased for the October show will be honoured on Sept. 9, but those who are unable to attend because of the change can receive a refund from Ticketmaster.
