Pete Crow-Armstrong hit a tiebreaking two-run homer for his first major league hit, and the Chicago Cubs swept the Houston Astros with a 3-1 victory on Thursday.

Nico Hoerner had three hits and Mike Tauchman went 1 for 1 with three walks as Chicago won for the fourth time in five games. Hayden Wesneski (2-0) pitched 2 1/3 perfect innings for the win in relief of Javier Assad.

Houston has lost a season-high five straight and eight of nine overall. At 7-19, it is off to its worst 26-game start since it was 6-20 in 1969.

First-year manager Joe Espada was ejected by plate umpire Jansen Visconti in the top of ninth.

Crow-Armstrong was recalled from Triple-A Iowa when Cody Bellinger was placed on the 10-day injured list on Wednesday with two fractured ribs. The 22-year-old outfielder, who is considered one of the team’s top prospects, made his big league debut last year and went 0 for 14 while appearing in 13 games.

He picked a perfect time for his first major league hit.

Houston had a 1-0 lead before Dansby Swanson scampered home on a fielder’s choice grounder for Miguel Amaya in the sixth.

Espada then replaced Rafael Montero with Bryan Abreu, who threw a wild pitch with Crow-Armstrong trying to sacrifice Amaya to second. Crow-Armstrong then drove his next pitch deep to right, delighting the crowd of 29,876 at Wrigley Field.
