Pete Crow-Armstrong, who came into the game hitting .183, was 3 for 4 with a run and the go-ahead RBI as the Chicago Cubs defeated the Kansas City Royals 7-3 on Sunday.

Crow-Armstrong got two of his three hits and his RBI off Royals starter Cole Ragans.

The Cubs (51-56) are 12-8 in their last 20 games after going 3-9 in their previous 12.

Javier Assad (5-3) allowed three runs on five hits in six innings.

Ragans (7-7) took the loss, allowing four runs in 5 2/3 innings.

Nico Hoerner doubled in the third to tie it at 2-all.

The Royals (57-49) retook the lead in the fourth on a controversial home run. Freddy Fermin launched a long flyball down the left-field line that appeared headed to the foul pole. A fan wearing a Cubs hat reached over the railing from foul territory and caught the ball before left fielder Ian Happ had a chance. Fan interference was called, giving Fermin his fifth homer of the season.

The Cubs took their first lead in the sixth. Michael Busch hit a one-out double and then scored on David Bote's two-out double. Bote scored on Crow-Armstrong's single, ending Ragans' day.

Chicago added three insurance runs in the ninth, including Patrick Wisdom's second homer in as many days.

Chicago continues a six-game road trip with the first of three games in Cincinnati. The Cubs will RHP Jameson Taillon (7-5, 2.96 ERA) to the mound to face Reds RHP Carson Spiers (3-2, 3.83 ERA).
