The Washington Nationals defeated the Seattle Mariners 8–3 on June 13 at Nationals Park, exceeding the Vegas total of 9.5 runs with a combined 11 tallies. The Nationals' offense generated 10 hits and 7 RBIs while striking out 7 times, posting a .740 OPS despite a modest .245 batting average. Seattle managed just 8 hits and 3 RBIs with an identical strikeout total, their .718 OPS reflecting a similarly sluggish approach at the plate; both teams drew 3 walks apiece. Washington's pitching staff struck out 8 Seattle batters while allowing 8 hits and 3 earned runs, though a 4.71 ERA suggested some inefficiency. The Mariners' pitchers fanned 7 Nationals but surrendered 10 hits and 5 earned runs, a concerning 3.59 ERA that masked the damage inflicted. The home team's one defensive error did little to derail their victory, underscoring that run prevention—not pitching statistics alone—determined the outcome. Washington's offensive production and command advantage suggest momentum building in their division race.
