Washington, DC (Sports Network) - Standing on first base in the second inning, Gerrit Cole used his right hand to fist bump his first base coach and exchanged a few words behind his black batting glove if only to break up long, emotionless stares with the dirt surrounding the bag.

Cole saved his best work, and excitement, for the mound, where he shut down the Washington Nationals and led the Pirates to a 5-1 win in the second of a four-game series.

The 22-year-old rookie gave up one run on two hits in seven innings to snap a three-start losing streak. Cole (5-3) struck out four and walked one in addition to two hits and an RBI at the plate.

Pedro Alvarez slammed his 25th home run for the Pirates, who have won three in a row.

Taylor Jordan (0-3) took the loss after giving up five runs -- four earned -- on nine hits and a walk over 7 2/3 innings.

Wilson Ramos' home run was the only run for Washington, which has lost five in a row.
