Mariners manager Dan Wilson said that the series his team recently played against the Athletics in Sacramento was Seattle's best of the year. And it certainly was, as they swept their divisional rivals, winning by an aggregate score of 22-4 and regaining control of the AL West standings.

Beyond the victories, it was also impressive that in the 9-1 win, Julio Rodríguez hit his tenth home run of the season and Refsnyder his third. Last year, home run power was one of the reasons the Mariners came so close to the World Series. Currently, the Mariners are without Cal Raleigh due to injury, and they have a weekend series coming up against perhaps the hottest team in all of MLB.

The Mariners completed their sweep of the Giants on Thursday, winning each of their last five games and 10 of their last 11. Veteran Ildemaro Vargas is still surprisingly having the best season of his career, and on Thursday, his sacrifice fly tied the game, while a sacrifice fly by Perdomo gave the D-backs the lead. Then, in the ninth inning, reliable closer Sewald recorded the final outs for his 100th career save.
