PITTSBURGH (AP) — A resurgent J.A. Happ worked into the sixth inning, Aramis Ramirez hit a three-run homer and the Pittsburgh Pirates held off the Colorado Rockies 4-3 on Saturday night.

Happ and Ramirez, both acquired near the trade deadline to give the Pirates needed depth, helped Pittsburgh improve to 14-3 in their last 17 games. Mark Melancon gave up a two-run homer to Nick Hundley in the ninth but hung on for his 43rd save.

Happ (7-7) won his third straight decision after giving up one run and five hits in 5 2-3 innings. Ramirez sent a breaking ball from Chris Rusin (4-7) into the seats in left field in the first inning for his 13th home run of the season and second since rejoining the Pirates on July 25.

Rusin lasted six innings but fell to 1-5 since June 21. Hundley and Ben Paulsen had two hits each for Colorado.
