CHICAGO — The Chicago Cubs defeated the Colorado Rockies 6-3 at Wrigley Field on Thursday afternoon, extending their winning streak to four games at home and tightening their grip on second place in the NL Central. Dansby Swanson was the offensive catalyst, delivering a two-run double in the sixth inning that broke a 3-3 tie and gave Chicago the lead for good.

The Cubs, who entered Thursday's contest with one of the more productive home records in the National League this season, wasted little time establishing control. Seiya Suzuki contributed an RBI single in the third inning, and Ian Happ drew a crucial two-out walk to keep the rally alive before Swanson's defining moment in the sixth.

Colorado, struggling through another difficult campaign that has seen them sit at or near the bottom of the NL West standings, could not recover after their bullpen surrendered three unanswered runs in the final three innings. The Rockies' offense managed three runs on eight hits but left seven men on base, squandering multiple opportunities against Chicago's middle relievers.

Chicago's starter delivered five innings of three-run ball, and the Cubs' bullpen locked down the final four frames without allowing a run, combining for four strikeouts. Manager Craig Counsell praised the team's recent consistency after the game, noting the importance of capitalizing on home matchups against weaker divisional opponents during the stretch run.

The result continues a concerning trend for Colorado, who have now dropped seven of their last nine road games and remain among the worst run-differential teams in the National League. The series continues at Wrigley Field, with Chicago looking to complete a sweep and keep pace in the increasingly competitive NL Central race.
