Busch Destroys D-backs with Four-RBI Day as Cubs Dominate at Wrigley

The Chicago Cubs put on a masterclass in offensive execution on Sunday at Wrigley Field, dismantling the Arizona Diamondbacks 8-4 behind a dominant performance from Michael Busch that should have every National League team taking notice. This wasn’t just a win, it was a statement about who controls the NL Central in 2026.

Busch was absolutely relentless, driving in four runs while going 2-for-3 and serving as the primary architect of Arizona’s downfall. His bases-clearing triple in the fifth inning didn’t just score runs, it shattered any momentum the Diamondbacks could muster. When you’re facing a lineup this dangerous and you can’t pitch, you lose. It’s that simple.

Matthew Boyd was the perfect complement to Busch’s offensive fireworks. The Cubs’ starter went six innings, yielding just four hits and two earned runs while striking out five. He didn’t overpower anyone, but he didn’t need to. Boyd mixed his pitches, worked ahead in counts, and escaped trouble when the Diamondbacks threatened. This is veteran pitcher baseball at its finest, not flashy but devastatingly effective.

Arizona’s Pitching Collapse

Merrill Kelly’s performance was genuinely disastrous. The Diamondbacks starter lasted just 4.1 innings, surrendering eight hits and six earned runs. Three walks didn’t help matters either. By the time he exited, the Cubs had already seized complete control of the game. Torey Lovullo’s pitching staff looked outmatched from the opening pitch, unable to generate consistent swing-and-miss stuff against a Cubs lineup that was locked in and ready to pounce on fastballs over the plate.

Gabriel Moreno’s two-run homer in the second inning gave Arizona an early lifeline and temporarily kept the score competitive. But it proved nothing more than a consolation prize in what became a one-sided affair. Moreno had flashed genuine power on that fly ball to left-center, yet it ultimately meant nothing in the context of this lopsided contest.

Cubs’ Offensive Dominance

The Cubs’ lineup was comprehensive in its destruction. Moisés Ballesteros added his own two-run shot in the third inning, establishing early Cubs control. Carson Kelly contributed two RBI singles, proving that success doesn’t always require the home run ball. Ian Happ was his usual productive self, finding his way into scoring position multiple times. This is a team firing on all cylinders offensively.

Arizona did muster a late-game spark when Adrian Del Castillo cranked a two-run homer in the ninth inning, but by then the outcome was already determined. This was garbage-time heroics, meaningless nostalgia masquerading as relevance. The Diamondbacks had their chance to compete and simply came up short across every measurable category.

The Cubs improved to another impressive mark with their offensive firepower fully activated. If Chicago can maintain this kind of run production and Boyd continues delivering quality starts, they’re positioned to be a serious October threat. Conversely, Arizona’s pitching staff must do serious soul-searching after this performance. You cannot win in professional baseball when your starter can’t make it through five innings against a team like Chicago. The Diamondbacks leave Wrigley with nothing to show for their effort except disappointment and questions about their rotation depth heading into the season’s stretch run.

Sunday belonged entirely to the Cubs, who turned this matchup into a clinic on how to win baseball games in May.
