Nick Castellanos hit a three-run homer, Rodolfo Durán went deep for his first career hit, and Gavin Sheets also connected in the San Diego Padres' 7-4 win over the Seattle Mariners on Saturday. Walker Buehler (3-2) allowed two runs in five innings as San Diego improved to 5-0 this season against its West Coast rival. The Padres clinched the season series on Friday to secure the Vedder Cup, named after Pearl Jam frontman Eddie Vedder, who has ties to both cities.
