PITTSBURGH -- Gregory Polanco helped free a grounds crew member trapped underneath a billowing tarp, then hit a go-ahead triple in the eighth inning that sent the Pittsburgh Pirates past the San Diego Padres 3-2 Tuesday night.
Strong winds and rain caused the tarp to start swelling as the grounds crew at PNC Park struggled to cover the infield, and a worker was swallowed up. McCutchen, Polanco and Rodriguez came from the dugout to help pull the tarp off him.
It was 2-all when Rodriguez was hit by pitch from Joaquin Benoit (5-4) leading off the eighth. Polanco tripled with two outs, giving the Pirates their fourth straight win.
McCutchen doubled, singled and set a career high by extending his hitting streak to 14 games. He had a 13-gamer as a rookie in 2009.
Matt Kemp doubled in both Padres' runs in the third after resumed. San Diego lost its fourth straight game and was held to two runs or fewer for the seventh time in eight games.
McCutchen doubled home a run in the third and Jung Ho Kang tripled in the tying run in the fifth.
Pittsburgh starter Francisco Liriano allowed two runs and four hits in six innings with six strikeouts and a walk.
Padres starter Tyson Ross was pulled after the delay. He worked two scoreless innings.
Kemp and Clint Barmes had two hits apiece for the Padres.
