Chapman (3-2) blew his second straight save opportunity after converting his first eight chances this season. The 100 mph throwing left-hander walked pinch-hitter Delmon Young on four pitches to open the ninth.
Phillies pitcher Cliff Lee pinch ran and was caught trying to steal second base, but Chapman wouldn't record another out. Kratz, who entered the game in the third inning after Carlos Ruiz left with a strained right hamstring, pulled a 3-2 pitch over the seats in left to tie it 1-all.
Galvis followed by lining a 1-1 pitch just inside the foul pole in left.
Antonio Bastardo (2-1) pitched a scoreless ninth inning for Philadelphia.
