The big blow came during an uprising in which the Tigers send 11 men to the plate but collected only two hits. They scored twice on bases-loaded walks and added two more runs on Phillies errors.
Matt Tuiasasopo and Victor Martinez each drove in a pair of runs for American League Central-leading Detroit, which stayed three games ahead of second-place Cleveland with its third win in three games against Philadelphia.
Rick Porcello (8-6) went six innings, yielding three runs on seven hits. He walked two and struck out three.
Reliever Jake Diekman (0-1) was tagged with the loss as the reeling Phillies dropped an eighth straight overall.
Darin Ruf and Kevin Frandsen each went 2-for-4 with an RBI for Philadelphia.
