Jung Ho Kang scored on Corey Dickerson's sacrifice fly to cap a frantic ninth-inning rally off Kimbrel and lift the Pittsburgh Pirates to a 6-5 victory over the struggling Cubs on Wednesday night.

Kimbrel (0-1) came on to protect a one-run lead and pick up his second save since signing a three-year deal with Chicago. Instead, he trudged to the dugout with his teammate walked off with his first loss since joining the Cubs. The Pirates used a walk, a flare that turned into a double and some aggressive base running to win their third straight.

The closer walked Elias Diaz on a full count with one out. Kang followed with a double to right that Chicago's Willson Contreras couldn't track down. Diaz beat the throw to the plate from Chicago second baseman Addison Russell on Adam Frazier's fielders' choice. Kang sprinted home when Kyle Schwarber's heave from the left field following Dickerson's fly ball was late to set off a giddy celebration.

Starling Marte collected three hits for the Pirates. Frazier's streak of hits in seven straight at-bats ended in the first but he singled in the seventh. Melky Cabrera went 3 for 4 and delivered a two-run home run off Chicago starter Yu Darvish but was also thrown out at home by Contreras to end the eighth while trying to score on a single by Colin Moran.

All it did was set the stage for Pittsburgh's 21st comeback win of the season.
