SEATTLE (Interstat) — Emerson Hancock pitched seven innings of two-hit shutout ball and Mitch Garver hit a two-run homer in the fourth inning, powering the Seattle Mariners to a 4-0 victory over the Toronto Blue Jays on Sunday afternoon at T-Mobile Park.

Hancock, who improved to 6-4 with a 2.68 ERA, allowed only a double to Vladimir Guerrero Jr. in the first inning and a single to Ernie Clement in the second. He struck out five and walked two, retiring the final 12 batters he faced before leaving after the seventh. Gabe Speier pitched a scoreless eighth inning, allowing no hits and striking out one, to preserve the shutout.

The Blue Jays fell to 42-48 with their second straight loss in Seattle, while the Mariners improved to 47-44 and won for the fourth time in five games. Toronto managed only three hits and never advanced a runner past second base after the second inning.

Seattle broke a scoreless tie in the third inning. Victor Robles led off with a single to center, and J.P. Crawford drew a walk. After Randy Arozarena grounded out, advancing both runners, Cal Raleigh lifted a sacrifice fly to right field, scoring Robles to give the Mariners a 1-0 lead.

The decisive blow came in the fourth. Luke Raley led off with a flyout, but Cole Young reached base on a throwing error by shortstop Ernie Clement. Garver then launched a 1-1 pitch from Trey Yesavage over the left-field wall for his fourth home run of the season, scoring Young and extending the lead to 3-0. Yesavage, who took the loss and dropped to 4-4, allowed three runs, only two earned, on four hits over 5 2/3 innings. He walked two and struck out five.

Toronto had its best scoring chance in the sixth inning. Yohendrick Piñango drew a leadoff walk, but Nathan Lukes grounded into a double play. Guerrero then walked, but Kazuma Okamoto popped out to shortstop to end the inning.

The Mariners added an insurance run in the eighth. After J.P. Crawford struck out, Arozarena singled and Raleigh followed with a single to right, putting runners at the corners. Josh Naylor then grounded a single through the left side of the infield, scoring Arozarena to make it 4-0. Raley lined out sharply to right, and Young struck out to end the inning.

Toronto went down in order in the ninth. Lukes singled to center with one out, but Guerrero struck out swinging and Okamoto lined out softly to shortstop. Alejandro Kirk lined out to center to end the game at 2 hours, 11 minutes before an announced crowd of 37,415.

The Blue Jays’ three hits came from Guerrero, Clement and Lukes. Guerrero doubled in the first inning but was stranded. Clement singled in the second but was left on base. Lukes singled with one out in the ninth but was the final baserunner.

Seattle’s six hits came from Robles, Garver, Naylor, Arozarena, Raleigh and Raley. Naylor drove in the final run with his single in the eighth. Garver’s homer was the only extra-base hit for the Mariners aside from Raley’s first-inning double, which did not lead to a run.

Toronto had won the series opener Friday 2-0 on a combined two-hit shutout, but Seattle rebounded with an 11-0 rout Saturday and completed the series victory Sunday. The Blue Jays have lost three of their last four games, while the Mariners have won four of five.

Yesavage allowed the lone run in the third on the sacrifice fly, then saw the error lead to the two-run homer in the fourth. He departed after allowing a two-out single to Josh Naylor in the sixth but was lifted for a reliever after that. The bullpen kept the Mariners scoreless until the eighth, when the reliever gave up the two hits and the run.

Toronto will open a three-game series at San Francisco on Monday, while Seattle travels to Miami for a three-game set beginning Tuesday.

Interstat’s game simulator projected a final score of Seattle 6, Toronto 3, while the ELO system gave the Mariners a 53.60 percent probability to win. Seattle was installed as a pregame favorite with a spread of minus-1.5 and the total score of four runs went over the over-under line of 7.5.
