The Mariners are about to deploy an unorthodox pitching plan

The Mariners are shaking things up in their starting rotation.   With a crowded stable of six starting pitchers — Logan Gilbert, Bryan Woo, George Kirby, Bryce Miller, Luis Castillo and Emerson Hancock — Seattle revealed Tuesday that they will use a “piggyback” pitching plan through the All-Star break.   Instead of a traditional five-man or expanded six-man rotation, the Mariners will have each of their starters work in a piggyback setup, meaning they will either open the game or cover bulk innings behind another starter while skipping their usual start, helping the team manage workloads and keep all six starters involved.
