ALL ABOARD THE GRIMACE TRAIN — The New York Mets were held scoreless for five innings in Game 4 of the NLDS Wednesday against the Philadelphia Phillies.

But it only took one hit for Francisco Lindor to flip the script.

Lindor’s grand slam in the sixth inning gave the Mets a 4-1 series-clinching victory to advance to their first NLCS since 2015 and made him just the third player ever to hit a lead-flipping slam in the sixth inning or later to gain a series for their team.

“They were starved for the big hit all night,” radio play-by-play analyst Howie Rose said after the hit. “And Francisco Lindor has just prepared a feast!”

It was Lindor’s first home run of the postseason and provided the biggest moment in a Mets uniform for the Puerto Rican, nicknamed “Mr. Smile’, since his arrival in New York in 2021.

The goal came just six days after the Mets’ magical run reached its first milestone with Pete Alonso’s NL Wild Card Series home run against the Milwaukee Brewers.

While the on-field magic belongs to the likes of Lindor and Alonso, fans have also heaped praise on McDonald’s mascot Grimace off the field.

After the purple friendly giant threw out the first pitch at Citi Field on June 12, the Mets went on a seven-game winning streak and are 66-38 since.

The team gave Grimace his own purple seat at Citi Field and a New York subway car bears his image after he rode the train to a playoff game with Mets fans.

Whether it’s big hits or McDonald’s magic, the Mets certainly have something good going for them.
