J.P. Crawford and Eugenio Suárez both homered, Luis Castillo overcame a shaky beginning to pitch seven strong innings and win his first start since May 27, and the Seattle Mariners beat the Washington Nationals 8-4. Seattle opened its final homestand before hosting the All-Star Game next month and needed its offense to come through as Castillo wasn’t at his best early on. It started with Crawford, who joined Washington’s Lane Thomas as both hit leadoff home runs in the first inning for their respective teams. Castillo eventually settled down recorded six of his final 12 outs via strikeout.
