Game context

The Seattle Mariners enter the June 13 contest at Nationals Park with a 37-34 record atop the AL West, coming off a decisive 10-2 road win the prior evening. Seattle’s rotation features Luis Castillo against Washington’s Cade Cavalli, whose 3.88 ERA contrasts Castillo’s 5.16 mark. Key injury developments include Randy Arozarena’s day-to-day hamstring status, which could alter Seattle’s lineup and baserunning, alongside multiple Mariners on the IL. The Nationals sit at 35-35 and host the finale of a three-game set after surrendering double-digit runs. Recent series momentum, bullpen depth, and home-field factors shape trader assessments of the closely matched AL-NL interleague outcome.
