Taylor Swift -- Does Solid For Houston Astros ... Or Just Jinxed Them

The battle for Minute Maid Park is over ... and the Houston Astros have won -- with Taylor Swift agreeing to reschedule a concert date that would have conflicted with an Astros playoff game.

Swift was originally scheduled to perform at MMP on October 13th -- which could have conflicted with a playoff game if the team makes the post-season.

FYI -- the Astros were expected to suck this season, but managed to put together a 55-45 record so far ... and are just one game behind the Angels for control of the American League West.

But now, Swift has apparently agreed to move the date up ... with the Astros announcing her concert will now take place on September 9th instead.
