Hendricks (2-1) struck out two and walked three in easily his best start this year. The struggling Pirates managed just four singles off Hendricks and didn't reach third base until he was out of the game. Wade Davis worked a perfect ninth for his fifth save as the Cubs won for the sixth time in seven games.
Addison Russell doubled in the second off Cole (1-3) and scored when second baseman Alen Hanson airmailed first base on a Jason Heyward grounder, the Pirates' major league-high 20th error this season. They've also allowed 15 unearned runs, the most in the big leagues.
The miscue spoiled a terrific outing by Cole. He struck out eight without issuing a walk and retired 14 of his final 15 batters. It wasn't enough for Pittsburgh, which has lost six of eight.
