Willy Adames delivered the decisive blow on the 18th, hitting a grand slam for his 16th home run of the season as the San Francisco Giants beat the Seattle Mariners 7-0 at T-Mobile Park in Seattle, Washington, USA. It was the kind of swing that turned a tight game into a comfortable win, and it came in a performance that combined balanced pitching with timely hitting.
The Giants did not pile up offence in the way a dominant scoreline might suggest, finishing with eight hits, but they made their key moments count. Bryce Eldridge had already given San Francisco a lift with his ninth home run of the season in the bottom of the fifth inning, before the Giants added another run in the sixth when Cole Young could not field a ground ball hit by Luis Aráez.
Adames turns a solid night into a statement win
Then came the seventh inning, and Adames put the game out of reach. His grand slam off Nick Davia was the defining hit of the night, and it underlined why his bat matters so much to this lineup. The Giants were not simply winning because Seattle struggled; they were also punishing mistakes when the game was still there to be shaped.
Adames finished 3-for-4 with two hits by pitch, two runs scored and seven RBIs. For a club trying to stay steady over the course of the 2026 MLB regular-season, that is exactly the sort of production that changes the tone of an evening and gives the pitching staff room to settle in.
Balanced Giants keep control from start to finish
San Francisco’s pitching did the rest. The Giants limited Seattle to just two hits, with six scoreless innings helping to keep the Mariners off the board throughout the night. It was a complete team performance rather than a one-man show, even if Adames provided the moment everyone will remember.
There was also a positive night for Lee Jung-hoo, who had been in a slump of no hits in 10 at-bats before the game. He went 3-for-4, and with June 24 his last three-hit game against the Athletics, his batting average rose from 0.302 to 0.307 after the game. In the context of an MLB batting title chase, that matters too.
For San Francisco, though, this was mostly about control and clarity. The Giants handled Seattle, protected their lead, and let Adames finish the job with one emphatic swing. If this is the level of support around their top bats, they will feel they have a lineup capable of deciding games in a hurry.
