The Chicago Cubs score 19 runs and defeat the Seattle Mariners 19-2 on Sunday, avoiding a three-game sweep. Ian Happ and Pedro Ramírez each hit grand slams and each drives in five runs as part of a large Chicago offensive burst.

Chicago also receives additional power from Pete Crow-Armstrong, who hits a home run, and from Michael Conforto, who hits his 11th homer of the season with a leadoff shot in the third inning. The scoring includes a sequence in which Happ hits a two-out, two-strike, bases-loaded single that highlights the Cubs’ continued pressure after initial scoring. On the pitching and early damage, Mariners starter Bryce Miller issues three consecutive two-out walks before facing Happ.
