Entering the game in relief of starter Megill, José Buttó allowed consecutive two-out hits, including an RBI single. Then, a three-run home run by Washington Nationals catcher Riley Adams, his first of the season, narrowed the Mets’ lead to 7-6.

Dylan Crews homered off Tylor Megill in the second for Washington’s first run. Torrens had an RBI double in the fifth to make it 7-1. Parker, who went five innings and allowed all seven Mets runs, saw his ERA climb to 2.65.

Down six runs early, the Nationals rallied in dramatic fashion to stun the first-place Mets for an 8-7 victory on Sunday at Nationals Park after a Pete Alonso throwing error at first base.
