Mariners Deploy Miller-Castillo Piggyback Start vs. D-backs
Seattle will use Bryce Miller to open and Luis Castillo to finish in a tandem start Sunday, the third use of this strategy this season.

The Seattle Mariners are deploying a piggyback rotation strategy Sunday against the Diamondbacks, with Bryce Miller starting and Luis Castillo following from the bullpen. This is the third time the team has used this tandem approach. The arrangement stems from Miller returning from the injured list while Emerson Hancock has pitched well enough to hold his rotation spot. The piggyback setup is expected to pause after this outing for at least a couple of weeks.
