Mariners place Hancock on 15-day IL, shuffle rotation

The Mariners placed pitcher Emerson Hancock on the 15-day injured list with a left adductor strain, retroactive to Aug. 29, interrupting what had been a breakout season and prompting Nick Davila to be recalled from Triple-A Tacoma. Hancock, 27, owns a career-best 3.57 ERA through 25 starts this year, and Seattle is scrambling to fill his spot as it reshuffles a beleaguered rotation. Bryce Miller has oscillated between the bullpen and the rotation amid a rough stretch; with Hancock out, he could rejoin the rotation to start in Hancock’s place, depending on the plan for Boston. The rotation has been under constant reconfiguration this season, featuring six-man rotations and piggybacks as Seattle searches for stability, a problem amplified by Hancock’s injury. Davila, who debuted in May, provides additional depth, while Miller’s recent 7.19 ERA across eight starts underscores how fragile Seattle’s rotation has become. All of these moves come as the team tries to salvage a season that has seen persistent starting-pitching uncertainty and underperformance in several area of the rotation.
