CHICAGO (AP) — Mitch Keller pitched six effective innings, Nick Gonzales hit a key two-run single and the Pittsburgh Pirates beat the Chicago Cubs 3-2 on Sunday.

Jack Suwinski connected for another homer against Jameson Taillon as Pittsburgh closed out a 4-3 road trip by taking three of four from Chicago. Gonzales, Andrew McCutchen and Jared Triolo each had two of the Pirates’ 10 hits.

“Very proud to finish this road trip the way we did,” Pirates manager Derek Shelton said.

Keller improved to 3-0 with a 1.29 ERA in three May starts. The right-hander allowed two runs and two hits, struck out three and walked three.

Keller (5-3) has worked at least five innings in his past 41 starts, the longest active streak in the majors.

“Just trying to be as efficient as possible and give us as much length as possible,” Keller said.

Seiya Suzuki and Christopher Morel each hit a sacrifice fly for Chicago, which was held to 10 runs and 18 hits in the series. Taillon (3-2) was charged with three runs and six hits in 4 2/3 innings.
