SAN FRANCISCO (AP) Jake Arrieta continued his impressive pitching and Kris Bryant provided the power as the Chicago Cubs beat the San Francisco Giants 8-1 on Friday night.

The Cubs won in Arrieta's 22nd consecutive start going back to last season, with their ace going 16-0 over that stretch. They won on the road for the 24th time in 29 games as they snapped San Francisco's eight-game winning streak.

Cubs outfielder Jason Heyward left the game in the bottom of the first inning after crashing into the wall on a diving catch.

Heyward is under evaluation for an injury to his right torso abdominal region, the Cubs said.

Heyward chased a shot over his head off the bat of Denard Span, robbing the Giants' leadoff man of extra bases on the third pitch he saw from Arrieta (8-0).

Arrieta, who leads the majors with a 1.29 ERA, allowed four hits, struck out eight and walked one in seven innings.
