​SEATTLE — Well, THAT felt better.Ian Happ’s grand slam in the third inning gave the Cubs the lead and eventually they put together a 17-hit, nine-walk, 19-run pounding on the Mariners, winning 19-2 and salvaging the final game of the series.Things did not start out that way. Randy Arozarena, who hit the crushing walk-off homer Saturday evening, led off this one with a long ball off Shōta Imanaga, another “you have got to be kidding me” moment.Imanaga struggled through the first two innings, allowing another run on a throwing error by Carson Kelly, issuing a couple of walks and hitting a batter, and things just were not going well for him at all.Fortunately, things didn’t go well for Mariners starter Bryce Miller, either, and the Cubs gave him a parting gift for his 28th birthday today.

Not only did that bring the Cubs within one, it also put Conforto back into a tie with Kyle Tucker. Both players have 11 home runs this year.After Miller retired the next two Cubs, he walked the bases loaded, with Seiya Suzuki, Michael Busch and Alex Bregman all drawing bases on balls.That brought up Happ [VIDEO].

Happ grand slam facts from BCB’s JohnW53:Ian Happ’s grand slam was the Cubs’ . . .Sixth of the season (one more than all of last year and as many as in 2024)367th in the regular season since 1876343rd since 1901156th on the road since 1876sixth by Happ; his previous one was their first of last season, on April 18 at home vs. the Diamondbacks)…Happ now is among five players tied for the fifth-most slams in team history. The others are Javier Baez, Kris Bryant, Derrek Lee and Aramis Ramirez.Bill Nicholson, Sammy Sosa and Billy Williams hit eight. Ernie Banks hit 12.Happ’s blast seemed to let the entire team and fanbase exhale after the two walk-off losses the last two days.Imanaga, though, struggled in the third and after allowing hits to the first two Mariners he faced in that inning, he was removed for Aaron Civale, who retired the next three hitters without incident. About Imanaga’s brief outing, from John:Shota Imanaga’s 2.0-plus innings pitched was the shortest of his 80 career starts as a Cub. He had been lifted after 3.0 innings twice: June 21, 2024, at home vs. the Mets (10 runs on 11 hits, including three homers), and July 25, 2025, at the White Sox (seven runs on seven hits, including three homers).The game went 5-2 into the fifth, when Miller — who I was surprised was allowed to start that inning as he had thrown a ton of pitches — walked the bases loaded yet again, this time Pete Crow-Armstrong, Suzuki and Busch.Bregman hit into a force play that made it 6-2 [VIDEO].
