Cubs 8, Diamondbacks 4: Michael Busch Triples the Lead at Wrigley

The lead

May 3, 2026 - Chicago - The Chicago Cubs stayed nearly unbeatable on Clark and Addison, beating the Arizona Diamondbacks 8-4 behind Michael Busch's three-run triple and sacrifice fly, a two-run homer from Moises Ballesteros, and six innings of two-run ball from Matthew Boyd on a day Nico Hoerner returned to the lineup, per CBS Sports.

The win extended Chicago's home heater to 11 straight victories at Wrigley Field and nudged the Cubs to 22-12 overall-10 games over .500-while Arizona dropped a fourth consecutive decision to fall to 16-17.

How the game turned

Busch supplied the game's biggest swing with his bases-clearing triple, then helped manufacture an insurance run later with a sac fly. Ballesteros turned a 2-0 Boyd lead into a broader cushion with a two-run shot in the third as the Cubs squared up Merrill Kelly early.

Kelly (1-3) absorbed six runs and eight hits in 4 1/3 innings on the CBS line, a short night that forced Arizona to lean on its bullpen while Chicago's offense kept adding stress. The Diamondbacks threatened in the seventh with the bases loaded and two outs, but Ketel Marte struck out to leave the rally unfinished-a moment CBS highlighted as the missed hinge in a would-be comeback.

For Arizona, Gabriel Moreno and Adrian Del Castillo each launched two-run homers, supplying the primary answers once Chicago's middle innings threatened to turn the game into another Wrigley rout.

Pitching and matchup notes

Boyd (2-1) worked six innings and allowed two runs on a manageable pitch count, bridging to a bullpen that bent during Arizona's power bursts but did not break the lead entirely. Kelly's elevated ERA entering the day foreshadowed trouble against a Cubs lineup swinging with confidence.

Hoerner, back after sitting with neck tightness, went 2-for-5, signaling stability up the middle for a club in the middle of a historic home streak - the CBS recap reminded readers Chicago had not won 11 straight home games since 2008.

Bats that changed the board

Busch's triple and Ballesteros' homer did the early damage, while Hoerner's multi-hit afternoon showed how Chicago lengthens a lineup when its everyday second baseman is healthy. Moreno and Del Castillo kept Arizona within earshot on the scoreboard, yet Marte's whiff with the bags full stalled the best late chance.

AthX Engine fantasy angle

AthX Engine graded the Cubs at 15 team FP on May 3, matching Philadelphia for fifth on the slate, while Matthew Boyd added 16 pitching FP and Michael Busch paced Chicago bats with 10 hitting FP. Extended home winning streaks often correlate with repeated team-fantasy ceilings because comfortable pitching scripts and confident sequencing feed each other.

Daily fantasy totals from AthX Engine differ from dynamic pricing, but Chicago offered another night where both the rotation and lineup contributed usable fantasy separation.

What comes next

The Cubs chase a dozen straight at Wrigley when the schedule turns, while Arizona resets on the road needing cleaner first turns through the rotation. Boyd's steady line gives Chicago another data point that its summer blueprint can hold even when the opponent lands a few long balls.
