KANSAS CITY — The Chicago Cubs flexed their offensive muscle on Sunday, cruising to a 10-2 victory over the Kansas City Royals to claim the series two games to one. The win was powered by a pair of home runs from Ian Happ and Miguel Amaya, along with another steady performance from left-hander Matthew Boyd, who moved to 8-1 on the season.

Happ’s two-run homer in the sixth inning, his 20th of the year, broke the game open. The blast came off Royals reliever Easton McGee and pushed the Cubs’ lead to 7-2. Amaya added a three-run shot in the seventh, also against McGee, to put the game out of reach. The long balls were part of an 18-hit barrage that saw three Cubs — Happ, Alex Bregman, and Michael Busch — each finish with three hits.

Bregman chipped in with a pair of RBI singles, continuing his consistent production in the middle of the lineup. His first run-scoring hit came in the fourth inning, driving in Pete Crow-Armstrong to make it 4-0. The second came in the sixth, plating another run before Happ’s homer sent him home as well.

The Cubs wasted no time getting on the board. In the first inning, Michael Conforto lifted a sacrifice fly to score Busch, who had reached base with a leadoff single. The pattern repeated in the third: Conforto singled to bring in Busch again, and Nico Hoerner followed with an RBI single that scored Happ, stretching the advantage to 3-0.

Kansas City’s offense finally stirred in the bottom of the fourth. Starling Marte crushed his second home run of the season, a two-run shot that also scored Salvador Perez, cutting the Cubs’ lead to 4-2. But that was all the Royals would muster against Boyd, who settled in after the homer and retired 10 of the final 11 batters he faced.

Boyd’s line: seven innings, five hits, two earned runs, no walks, and four strikeouts. The veteran left-hander has been a revelation for the Cubs this season, consistently working deep into games and giving his team a chance to win. Sunday’s outing lowered his ERA to 2.91 and reinforced his status as a reliable arm in the rotation.

Royals starter Randy Dobnak took the loss, falling to 2-1. He went five innings, allowing four runs on ten hits with one walk and four strikeouts. Dobnak kept the game within reach for a while, but the Cubs’ relentless approach at the plate wore him down. Kansas City’s bullpen struggled to contain the damage, with McGee surrendering five runs in his two innings of work.

A notable subplot: the Cubs did not play their usual defensive alignment, with Busch starting at first base and Crow-Armstrong in center field. Manager Craig Counsell’s mix-and-match lineup paid off handsomely, as every starter except one reached base at least once.

Looking ahead, the Cubs travel to Washington to face the Nationals on Tuesday. Left-hander Shota Imanaga (8-9, 3.60 ERA) will take the mound, looking to continue the team’s momentum. The Royals, meanwhile, head to Los Angeles to begin a series against the Dodgers on Monday. They will send lefty Noah Cameron (6-8, 4.37 ERA) to oppose Tarik Skubal (7-6, 2.81 ERA) of the Dodgers.

For the Cubs, the series win in Kansas City represents another step forward in a season of resurgence. The offense has been clicking, the rotation is finding consistency, and the pieces are falling into place for a potential playoff push. Sunday’s performance was a testament to what this team can do when everything clicks.
