A.J. Burnett worked around five walks while pitching seven innings, and the Pittsburgh Pirates stopped a four-game losing streak by cooling off the Chicago Cubs with a 3-0 victory on Sunday.

Burnett allowed three hits and struck out seven while handing Jake Arrieta his first loss in six career starts against Pittsburgh. Burnett (3-1) has allowed two runs or less in each of his eight starts this year after losing 18 games with Philadelphia last season.

Francisco Cervelli had a hand in Pittsburgh's first two runs after the catcher was shaken up in the fourth when he was hit in the groin by a foul tip. He had an RBI single in the fifth, and then singled and scored on Neil Walker's two-out double in the eighth.

The Cubs had won six in a row and seven of nine. Rookie third baseman Kris Bryant was pulled after four innings, and the team said he was ill.
