NEW YORK – With the bases loaded in a potential series-clinching Game 4 of the NL Division Series, Francisco Lindor needed only 4.4 seconds to turn Citi Field into a wild eruption of exclamations and cheers.

Lindor blasted his second career postseason grand slam off Phillies reliever Carlos Estévez in the sixth inning to give the Mets the lead over the Phillies on Wednesday in their eventual 4-1 win, the Mets' first series-clinching victory at home since Citi Field opened in 2009.

A 2-1, 99.4 mph fastball in the zone from Estévez quickly became one of the most significant of Lindor’s career. Lindor rocketed it 398 feet to center field at 109.5 mph to send the crowd into a frenzy.

On the Mets' radio broadcast, Howie Rose put words to the pandemonium: "Swing and a drive toward the gap in right-center; it's pretty deep! It's back near the wall! It's gone! It's gone! Francisco Lindor! He may have just outdone himself! He's hit a grand slam into the Phillies' bullpen in right-center field!"

The Mets had loaded the bases in the first and second innings but could not plate a run, leaving eight runners on through the first five frames. Rose made note of that:

"They were famished for the big hit all night, and Francisco Lindor just provided a feast!"

Lindor joined Edgardo Alfonzo as the only Mets players to hit a postseason grand slam.

While with Cleveland, Lindor also hit a grand slam in Game 2 of the 2017 AL Division Series against the Yankees.

The Mets loaded the bases against the Phillies’ bullpen after Ranger Suárez delivered 4 1/3 scoreless innings. J.D. Martinez singled to center field off Jeff Hoffman and advanced to second base on a wild pitch. Starling Marte was hit by a pitch from Hoffman, and both runners advanced on another wild pitch. Tyrone Taylor drew a walk to load the bases for Francisco Alvarez, who grounded into a forceout to home.

But when the Phillies called for Estévez with the bases still full, Lindor delivered.

Lindor’s slam was the Mets’ second go-ahead homer this postseason while training in the sixth inning or later, joining Pete Alonso’s three-run homer in Game 3 of the Wild Card Series. The club had only one such home run in franchise history prior to this year, in 1986 by Lenny Dykstra in Game 3 of the NLCS.
