The Seattle Mariners are returning to a piggyback starting rotation strategy for the next month, effective immediately. This plan will rotate all six starters, allowing each to pair with another starter to manage pitching loads. General Manager Justin Hollander praised the rotation's camaraderie and willingness to collaborate through recent pitching struggles and injuries. The decision follows a 4-6 road trip where the team's bullpen was stretched thin, impacting the performance of starters like Emerson Hancock and George Kirby. The first pairing under the new strategy will feature Luis Castillo and Bryce Miller sharing a start on Friday.
