Ian Happ and Christopher Morel each had three hits and two RBIs and the Chicago Cubs used a five-run fifth inning to rally for a 7-2 home victory over the Pittsburgh Pirates on Thursday, completing a three-game sweep.

Chicago's Marcus Stroman (8-4) allowed two runs over six innings to win his sixth straight start. Stroman, who gave up a pair of third-inning runs, yielded four hits and walked two but struck out five to record his major-league-leading 13th quality start.

Nico Hoerner had two hits and two runs and Cody Bellinger returned from missing a month with a left knee contusion to drive home the tiebreaking run in the fifth as the Cubs completed their first home sweep of 2023. Chicago won for the fifth time in six games overall.

Jason Delay had two hits for Pittsburgh, which leads the National League Central but has dropped six of eight. Pirates starter Johan Oviedo (3-6) was charged with four runs while allowing eight hits and one walk over 4 1/3 innings. He fanned eight.

Pittsburgh jumped in front in the third. Ji Hwan Bae singled, went to third on Delay's opposite-field knock to right and scored on Tucupita Marcano's line-drive single to center. Delay eventually scored on Carlos Santana's groundout.

Chicago cut the 2-0 deficit in half in the bottom of the third. Oviedo walked Hoerner, who stole second and scored on Happ's single.

That duo came through again in the fifth, when Hoerner singled and scored on Happ's double into the left field corner to tie the game. Then with Pittsburgh's Jose Hernandez on the mound, Bellinger drove in Happ with a double to give Chicago the 3-2 lead.

Morel plated another run on a liner off third baseman Ke'Bryan Hayes' glove, and Bellinger scored on Nick Madrigal's safety-squeeze bunt.

Hoerner, though, wasn't through in the fifth. A run scored on his grounder that was booted by Marcano at shortstop.

The Cubs added another run on Morel's sacrifice fly in the sixth.
