NEW YORK (AP) — Deadline acquisition Tyler Naquin homered twice in his home debut, Edwin Diaz locked down his first two-inning save as a pro and the New York Mets beat the Atlanta Braves 6-4 to open a pivotal five-game series between the NL East rivals.

Pete Alonso and Daniel Vogelbach hit back-to-back homers in the third for the Mets, who extended their lead over the Braves to 4 1/2 games.

Alonso, who began the scoring with a single in the first, finished with three RBIs.

Naquin, acquired from the Cincinnati Reds last Friday, hit solo shots in the second and sixth off Kyle Wright.
