The Phillies let down the FLOTUS in a big way on Wednesday night ... not only losing to the Astros in front of Jill Biden -- but doing so in historically awful fashion.
Biden hit Citizens Bank Park full of hope for the World Series' Game 4 ... but it didn't take long for her beloved Philly squad to disappoint.
In nine innings, the team didn't record a hit -- marking only the second time EVER that a squad has gone hitless in a Fall Classic game. Philadelphia ended up losing, 5-0.
