Overview
- The Mariners removed assistant hitting coach Bobby Magallanes and elevated minor‑league hitting coordinator Ed Paparella to the major‑league staff for the rest of the season.
- Team leaders Kevin Seitzer and director of hitting Edgar Martinez remain in their roles so the change adjusts staff voice rather than overhauling hitting leadership.
- The decision targets a pronounced offensive slide — Seattle ranks near the bottom of MLB in batting average, OPS and runs per game — while the club sits around .500 in the standings.
- Magallanes, a popular bilingual clubhouse presence who focused on mechanical fixes, was in his second season in Seattle and his dismissal follows injuries to key hitters such as Cal Raleigh, Julio Rodríguez and Brendan Donovan.
- Paparella, 31, has been with the organization since 2021 as a roving minor‑league coordinator who has worked with the team’s high‑performance and analytics groups and this promotion signals an internal, development‑driven approach; the club is also expected to weigh roster moves to add right‑handed power.
