The Yankees and Mets will battle for New York bragging rights when they meet for a three-game series at Citi Field beginning on Friday

In the top of the ninth inning Friday at Citi Field, Jeff McNeil splayed himself onto the outfield grass, belly flopping in an attempt not only to save a hit, but to keep Aaron Judge out of the batter’s box one last time.

Jeff McNeil hit a go-ahead, two-run homer off Luke Weaver in the seventh inning, leading the New York Mets over the Yankees 6-5 on Friday in a Subway Series opener between teams that faded badly after strong starts.
