PHOENIX (AP) The newest additions to the Washington bullpen came through when called upon to help deliver a victory to their new team.

Sean Doolittle stranded the potential tying run by escaping a jam for his second save for Washington, and Ryan Madson tossed a scoreless eighth inning as the Nationals held off the Arizona Diamondbacks 4-3 on Saturday night.

"The game can really speed up on you once you start getting guys on base," said Doolittle, who with Madson arrived in a trade with Oakland earlier in the week. "The crowd and the energy of the stadium can kind of take over and ... you have to be mindful enough to step off the mound, slow the game down a bit, kind of press reset."
