Marsh singled in the second inning, hit a two-run homer in the fourth, drove in two runs with a fifth-inning single and got another base hit in the eighth.
Phillies starter Spencer Turnbull, facing the Tigers for the first time after spending five seasons with them, allowed one run in three innings before leaving with right shoulder soreness.
He said the problem started on his next-to-last pitch.
“I threw a curveball and I felt something grab back in my triceps/shoulder area,” he said.
“It just got a little tight, but I didn’t want to do anything to make it worse.”
For Turnbull, it was yet another injury at Comerica Park.
“I don’t know what it is about this place, but I can’t seem to stay healthy here,” he said. “I don’t know if it is cursed or what.”
They threw great up and down the line,” Phillies manager Rob Thomson said. “It was a really good game, and we should be close to a full bullpen for tomorrow.”
Keider Montero (0-2) entered the game for Detroit in the fourth inning and allowed five runs and five hits and three walks.
The Tigers are 4-8 in their past 12 games, getting held to two runs or fewer nine times, including an 8-1 loss to the Phillies in the series opener.
