Pete Crow-Armstrong homered and Matthew Boyd tossed six strong innings as the Chicago Cubs completed a three-game sweep of the visiting Colorado Rockies with a 2-1 victory on Wednesday night.

Seiya Suzuki doubled in a run and Matt Shaw had two hits for Chicago, which has won four straight games and 10 of its last 12.

Boyd (5-2) allowed one unearned run on four hits with no walks and eight strikeouts. Ryan Brasier and Brad Keller each pitched a scoreless inning before Daniel Palencia retired the Rockies in order in the ninth for his fourth save.

Colorado lost its third straight and fell to 9-47, the worst start to a season in baseball’s modern era (since 1901). Orlando Arcia had two hits in his debut with the Rockies after signing as a free agent earlier in the day.

The Rockies were swept in a series for the ninth time this season and have lost 18 consecutive series to begin the 2025 campaign.

Chicago took a 1-0 lead in the first inning when Kyle Tucker scored from first on Suzuki’s one-out double against Tanner Gordon (1-2).

Crow-Armstrong added to the Cubs’ lead with a leadoff homer in the fourth inning. The 379-foot shot to right field was his team-leading 15th homer this season.

Gordon gave up two runs on six hits over 4 2/3 innings. He struck out one and did not allow a walk.

Colorado pushed a run across in the sixth inning. Mickey Moniak hit a leadoff single, moved to third with one out on Boyd’s errant pickoff throw, and scored on Tyler Freeman’s sacrifice fly.

The Rockies put two runners on with one out in the fifth inning, but Boyd escaped unscathed when Michael Toglia grounded into a double play.

Chicago won its sixth straight game at Wrigley Field behind another strong showing from its bullpen. Keller extended his streak of not allowing an earned run to 18 innings over his last 16 games.

Colorado was held to six singles and fell to 2-14 since Warren Schaeffer replaced Bud Black as manager on May 11.
