Mariners complete a late comeback to end Giants’ win streak with a walk-off

The Giants’ attempt to string together momentum ended abruptly in Seattle, where a walk-off loss snapped their three-game winning streak. The game followed a familiar pattern for San Francisco this season, one in which promising swings have often been undercut by late-game execution on the mound and in the field.

According to the Yahoo Sports report, the Mariners’ comeback featured a pivotal burst from their lineup in the middle innings. Cole Young hit a three-run home run in the seventh inning, a swing that helped Seattle turn the game back toward itself as San Francisco’s advantage started to slip.

From there, the outcome tilted decisively toward the Mariners. The defining moment came at the end, when Seattle secured the game on a walk-off, leaving the Giants to absorb a second straight lesson about closing out tight contests.

The loss is another reminder of how narrow margins are in Major League Baseball, where a single inning can rewrite the feel of the night. For the Giants, whose win streak had provided a rare stretch of stability, the walk-off outcome erases the immediate payoff of their recent form.

For the Mariners, the victory carries a different kind of value. Come-from-behind wins can tighten a clubhouse belief system, especially when the performance is anchored by a specific offensive moment like the seventh-inning home run reported by Yahoo Sports.

Looking ahead, the key for San Francisco will be reducing late-game vulnerability. Whether the issue is pitch-to-contact quality, defensive sharpness, or base-running judgment, the Giants now have another data point from a late turnaround. For Seattle, the watch item is consistency, the ability to convert similar situations into wins even when the game state changes quickly.

At this stage, the full statistical breakdown, the final score, and the exact sequence of the walk-off play were not provided in the available reporting excerpt. A complete box score and recap will be necessary to place the game’s turning points precisely and to confirm every inning-by-inning detail.
