By blanking the Blue Jays, the Mariners celebrate their return to the postseason.

The Seattle Mariners defeated the Toronto Blue Jays 4-0 on Friday in the first game of their AL wild-card series. Luis Castillo and Andrés Muoz combined for a shutout, Cal Raleigh hit a two-run home ball, and it was the Seattle Mariners’ first postseason victory since 2001.

The Mariners, who can win the series with a victory in Game 2 on Saturday, were led by rookie Julio Rodrguez, who reached base three times and scored twice, and Eugenio Suárez, who had two hits and two RBIs. In the Division Series, which begins on Tuesday in Texas, the series victor faces the winner of the AL West, Houston.

In 7 13 innings, Castillo misfired on six hits. While playing against the AL’s second-highest scoring team, he struck out five while walking none.
