The Seattle Mariners are reviving the piggyback strategy in their pitching rotation, making a significant change by involving all six of their starters. General manager Justin Hollander announced that each starter will participate in a tandem outing, sacrificing an inning or two over the next month. This strategy aims to maintain normal rest for the pitchers while adapting to the upcoming schedule. The first piggyback outing is set for this Friday against the Boston Red Sox at T-Mobile Park, with Bryce Miller starting and Luis Castillo following in relief. The Mariners' rotation will also include Bryan Woo, Logan Gilbert, Emerson Hancock, and George Kirby, who will contribute to the remaining piggyback outings. Hollander emphasized the importance of structuring the rotation in advance to accommodate any unforeseen circumstances, such as illness. The shift from a straight six-man rotation comes as the Mariners face multiple off-days leading up to the All-Star break, which could disrupt the regular pitching routine. By implementing this piggyback strategy, the Mariners aim to enhance their pitchers' performance and maintain their development throughout the season.
