The Washington Nationals returned home Friday night after a long three-city road trip.
But the struggles continued for the defending National League East champions, who lost 5-4 to the red-hot Arizona Diamondbacks.
The Nationals (11-15) have now lost five of their last six games and are just 3-8 at Nationals Park this year.
Nationals third baseman Wilmer Difo, playing for the injured Anthony Rendon, drove in a run on sacrifice fly in the fifth inning to give Washington a 4-3 lead.
But first-place Arizona (18-7) responded with two runs in the sixth, taking a 5-4 lead on an RBI triple by A.
