Phillies' Spencer Turnbull Placed on Injured List with Lat Strain

Right-hander exits start early; rookie Michael Mercado likely to fill rotation spot.

Turnbull left Wednesday's game against the Tigers after 36 pitches due to a lat strain.
He had moved to the starting rotation to replace Taijuan Walker, who is also on the injured list.
Turnbull has a 2.65 ERA this season, excelling as a starter with a 1.78 ERA in seven starts.
Rookie Michael Mercado is expected to step into the rotation after recent success in Triple-A.
Yunior Marte was recalled from Triple-A to bolster the bullpen in Turnbull's absence.
