The Tigers have a tough decision to make between the two for a rotation spot.
"It's a good problem to have, there's no question about that," manager Brad Ausmus said. "It ultimately makes it a tough decision."
A day after Boyd seemingly staked his claim by tossing five scoreless innings against a Braves lineup stocked with regulars, Sanchez answered with six hitless innings Saturday against a Pirates lineup that included Josh Harrison, Andrew McCutchen, Starling Marte and Francisco Cervelli. An error and a walk -- Sanchez's first walk since March 4 -- comprised his only baserunners in the Tigers' 5-4 loss.
