Overview

• Josh Naylor was named to Seattle’s 26-man ALDS roster and was in the Game 1 lineup, though he is ready to leave if his wife goes into labor in Arizona.
• MLB’s postseason paternity policy permits an absence of up to three days and allows a temporary roster replacement during that span.
• The Mariners have worked Eugenio Suárez at first base, carried rookie Ben Williamson for infield depth, and identified Luke Raley as a first-base option.
• The Seattle Times reported the due date aligns with Game 1, underscoring the real-time uncertainty around Naylor’s availability.
• Naylor has delivered a .299/.341/.490 line with nine homers, 33 RBIs, and 19 steals in 54 games for Seattle since the trade, and he is a pending free agent this offseason.
