Kyle Tucker launched a three-run homer and matched a season high with four hits against the team that traded him in December, and the Chicago Cubs routed Houston 12-3 on Saturday night to stop the Astros' five-game winning streak.

Tucker also scored four times to pace a Cubs lineup that pounded out 15 hits, including three by Dansby Swanson. Seiya Suzuki, Michael Busch and Nico Hoerner also went deep.

Chicago hit three homers in an inning for the second time this season during a seven-run fourth. Busch and Hoerner had back-to-back solo shots to put the Cubs on top 3-2, and Tucker’s drive made it 7-2.

The offensive outburst came in support of Colin Rea (5-3), who allowed two runs and five hits over five innings. The only blemish on his line was rookie Cam Smith’s two-run homer in the third, which briefly gave the Astros a 2-1 lead.

Smith, part of the package Houston received for Tucker, finished with two hits and has homered in consecutive games for the first time in his career.

Lance McCullers Jr. (1-3) came off the injured list and allowed eight runs on seven hits over 3 1/3 innings.

Isaac Paredes, also part of the Astros' trade return for Tucker, hit his 17th home run.
