Giants three-game win streak snapped in brutal walk-off loss to Mariners

SEATTLE — It has been a season-long struggle for the Giants to build any kind of momentum, usually thwarted just as things get good by subpar pitching or poor defense.Once again, it was the same culprits that kept them from extending a three-game winning streak to four.The Giants got home runs from Rafael Devers and Willy Adames and six shutout innings from Logan Webb on Saturday but still fell to 0-6 when going for their fourth win in a row. The second hit Webb surrendered was a three-run home run that tied the game in the seventh, and after the Giants weren’t able to push across their automatic runner in extra innings, Julio Rodriguez sent them to a 4-3 walkoff loss with a sacrifice fly off Dylan Smith in the 10th.The Giants led 3-0 when Webb served up the game-tying homer to Cole Young, and almost on cue, Luis Arraez flubbed a grounder from the next batter for only his fifth error, which proved inconsequential in the outcome but was tinged with symbolism.When Webb took the mound to begin the seventh, he seemed poised to take it to the finish line.
