SEATTLE (AP) — Shota Imanaga allowed one unearned run over 5 1/3 innings, Michael Busch homered in his third straight game and the Chicago Cubs beat the Seattle Mariners 4-1 on Saturday night.

Seiya Suzuki and Miguel Amaya also hit solo home runs for the Cubs. But the focus was on Imanaga (2-0) continuing the excellent start to his major league career, and some timely defense from third baseman Christopher Morel in the sixth to keep the Cubs in front.

Morel made consecutive outstanding plays with runners in scoring position, first diving to stop Mitch Garver’s hard grounder from getting down the left-field line and then leaping to snag Dylan Moore’s line drive.

“That changes the game right there. They may have the lead if that ball gets into the corner,” Cubs manager Craig Counsell said of the first play Morel made. “That was a huge play. He made some really nice plays tonight. Overall it was definitely a really big defensive game for Christopher.”
