Guillorme, pinch-hitting for Mark Canha with automatic runner Brett Baty at second, failed to put the ball in play on consecutive bunt attempts against Nick Robertson (0-1). Guillorme then doubled down the first base line past a drawn-in Freddie Freeman to easily score Baty.
It was Guillorme's first career walk-off hit.
David Robertson (4-2) allowed one hit over two scoreless innings and stranded automatic runner James Outman at third in the top of the 10th by getting Will Smith to ground out and retiring Mookie Betts on a long flyout.
Brandon Nimmo had an RBI groundout in the fifth for the Mets, who received seven innings of one-hit ball from Max Scherzer. The right-hander, who gave up a second-inning single to Jason Heyward, walked three and struck out six over seven innings. It was the seventh time Scherzer has thrown at least seven innings and allowed one hit or fewer, tied for the 14th most all-time
Betts had a game-tying RBI single in the eighth. Dodgers starter Bobby Miller gave up one run on three hits and one walk while striking out five over 4 2/3 innings
The Mets built their first run in the fifth. Starling Marte led off with a single and stole second as Baty struck out. Canha was then plunked by a pitch and Omar Narvaez drew a walk before Marte scored on a groundout by Nimmo, whose comebacker glanced off Miller's glove and left the pitcher no chance at turning a double play
The Dodgers tied the game against Trevor Gott in the eighth. Outman drew a leadoff walk, went to second on a single by Miguel Rojas, advanced to third on Smith's flyout to right and scored on Betts' single to left
