MLB.com Phillies beat writer Todd Zolecki provides the numbers:
Phillies attendance tonight is 39,475. First time they’ve had less than 40,000 since April 29, 2009, when they had 36,351 vs. WSH.

39,475 is still a fine total and one that most organizations would be ecstatic about, but this was on a Saturday night and it was only the Phillies’ second home game. So it’s easy to imagine the situation worsening.
The Phillies will carry a 2-3 record into Sunday afternoon’s series finale against the Royals.
