Billy Hamilton singled home the go-ahead run in the 14th inning for his first hit as a Brave, and Atlanta beat the host Mets, 2-1, on Friday night for its sixth straight win despite yet another sensational game by Jacob deGrom.

The Mets tied a major league record by striking out 26 batters — including 13 by deGrom — but had their five-game winning streak end.

At 21, the Braves’ Ronald Acuna Jr. became the second-youngest player with a 30-homer, 30-steal season. Only Mike Trout did it faster than Acuna.

A speedy baserunning specialist, Hamilton was claimed by Atlanta off waivers from Kansas City last week to be a late-game contributor for the Braves — although not with his bat. Hamilton entered as a pinch-runner in the 10th and stole a base but was left stranded.
