Seattle Mariners fall 6-5 in extra innings to Marlins on July 7

Seattle Mariners suffered a 6-5, 10‑inning defeat to the Miami Marlins on Tuesday night, July 7, 2026, as Jakob Marsee delivered a walk‑off single in the bottom of the tenth. The loss leaves Seattle at 47-46, third in the American League, and on a two‑game skid after a 2-0 loss in Miami on July 8.

What happened in the game?

Marsee’s high drive off the wall in right field snapped a tense extra‑inning battle, scoring automatic runner Xavier Edwards and sealing the win for Miami. Seattle had rallied in the eighth, loading the bases and tying the game at five after a 422‑foot homer by pinch‑hitter Heriberto Hernández. Cal Raleigh’s two doubles powered the Mariners’ three‑run surge, but a wild pitch later let the winning run cross the plate.

Who were the key contributors?

RHP George Kirby (7-7, 3.81 ERA) started for Seattle and gave up three runs over five innings, while Marlins’ starter Tyler Phillips (1-3, 3.52 ERA) allowed four runs in six. Raleigh doubled twice, including a two‑bagger that drove in a run in the eighth. Josh Naylor added a chopper that scored Randy Arozarena, and Cole Young homered in the fifth to spark the comeback.

How does this affect Seattle’s season?

The defeat drops the Mariners to a 47-46 record, keeping them third in the AL but extending a two‑game losing streak. Their last outing was a 2-0 shutout loss at Miami on July 8, highlighting offensive struggles that need fixing before the playoff push. Pitching depth will be tested as they prepare for the next series.

What’s next for the Mariners?

Kirby is slated to return to the mound on Wednesday against the Marlins, hoping to rebound from the extra‑inning loss. Manager Scott Servais will likely shuffle the bullpen to protect the lead, while the lineup may see adjustments to spark the offense that has sputtered in recent games. Seattle’s next road trip could determine whether they climb back into contention or slip further down the standings.
