CHICAGO (Interstat) — Spencer Arrighetti pitched into the sixth inning, Christian Vázquez drove in two runs and the Houston Astros defeated the Chicago Cubs 4-2 on Friday afternoon at Wrigley Field, snapping a modest two-game losing streak while dealing the Cubs a fourth consecutive defeat.

Arrighetti (6-1) allowed two runs on four hits over six innings, striking out five and walking three. He escaped an early jam in the third inning when the Cubs loaded the bases with no outs on a walk, a hit batter and another hit batter, but Arrighetti struck out Ian Happ, got Seiya Suzuki to pop out on the infield fly rule and induced a groundout from Michael Conforto to keep the game scoreless.

Bryan King worked a perfect ninth inning, striking out one, to earn his fifth save. Jameson Taillon (2-4) took the loss after allowing four runs on eight hits in four-plus innings. He walked one and struck out four.

Houston took the lead in the third inning when Vázquez led off with a solo home run, his fourth of the season, to left-center field. The Astros padded the advantage in the fourth. Christian Walker led off with a single, Braden Shewmake walked and Cam Smith singled to load the bases with no outs. Zach Cole then grounded into a force out that scored Walker, and Vázquez followed with a two-out single to right field that brought home Shewmake, making it 3-0.

The Astros added another run in the fifth. Isaac Paredes singled, Yordan Alvarez singled to put runners at first and second, and after a flyout and a force out, Brice Matthews ripped a sharp line drive to center field that scored Paredes, stretching the lead to 4-0.

Chicago got on the board in the sixth inning. Miguel Amaya led off with a single to center field, and one out later, Pete Crow-Armstrong launched a two-run homer to right field, his sixth of the season, cutting the deficit to 4-2. Crow-Armstrong also doubled earlier in the game.

The Cubs threatened again in the eighth inning. Carson Kelly was hit by a pitch from left-hander Steven Okert, and Crow-Armstrong walked. After a pitching change, Dansby Swanson reached on a throwing error by shortstop Jeremy Peña, loading the bases with one out. But Nico Hoerner grounded into a force out at second base, with shortstop Brice Matthews relaying to first to end the inning. Enyel De Los Santos, who relieved Okert, retired the final two batters of the inning and struck out one in 1⅔ shutout innings. Bryan Abreu also contributed ⅔ of a scoreless frame.

The Astros had opportunities to add insurance in the ninth inning but failed to score. With two outs, Paredes walked and Alvarez walked, but Walker struck out swinging to end the inning. King then retired the Cubs in order in the bottom half, sealing the win.

Key offensive performances for Houston included Vázquez, who went 2-for-4 with a home run and two RBIs. Matthews, batting as a pinch hitter and then playing second base, went 1-for-2 with an RBI. Paredes finished 1-for-4 with a walk, while Peña singled in his first at-bat and finished 1-for-5. Jake Meyers singled and scored a run. For Chicago, Crow-Armstrong had the two-run homer and a double, while Amaya singled. The Cubs managed only four hits overall.

The Astros improved to 21-31, while the Cubs fell to 29-22. Attendance was announced as 37,332. The game lasted 2 hours, 57 minutes.

Houston had lost two of three in Minnesota earlier in the week, including a 4-1 defeat Wednesday, after splitting a weekend series with Texas. The Cubs entered on a three-game losing streak after being swept at home by Milwaukee.
