WATCH: Bryce Harper Replies to a Heckler before Launching a Spectacular Walk-off Grand Slam

In what became on of the hottest ties of the Major League Baseball (MLB) 2019 season, Chicago Cubs and Philadelphia Phillies race for the play-offs intensified when the Phillies outfielder Bryce Harper spat out at a heckler.

A heckler told Bryce Harper he was “$330M, 0-for-3.”

Harper, in reply, said,  “shut the f**k up.”

The shout became even more dramatic, when Harper, immediately after his angry reply hit a stunning walk-off Grand Slam, which eventually sealed the victory for his team.

The Phillies were 5-3 down when Harper crushed a 95 mph inside pitch from Chicago Cubs pitcher Derek Holland into the stands for an extra-ordinary walk-off grand slam.

MLB researcher David Adler tweeted that the hit, with an initial speed of 113 mph, attained a maximum height of 158 feet and a covered a distance of 413 feet in a flight duration of 6.7 seconds.

Harper, understandably, seemed extremely delighted after the mammoth hit.

“Winning a division, getting to the playoffs, things like that, of course, are great things,” Harper said in a post-game interview.

“But being able to hit a walk-off homer like that is what you live for. That was one of the coolest moments I’ve ever had in my life,” said Harper of the walk-off home run.

The hit unfortunately wasn’t viewed by his parents.

“I saw my parents’ lights were off in the suite right now, so they probably didn’t see that,” Harper was quoted as saying. “So, thanks, Mom and Dad. Appreciate ya’.”

Harper, after hitting the huge hit, sprinted around the bases with a huge smile before celebrating with fellow players.

His wife Kyla Harper, who was supposedly watching the entire scene, jokingly wrote on twitter about his running speed rather than the outstanding walk-off grand slam.

“Never have I ever seen him do this grinch like sprint but it’s a vibe I never knew I needed,” she tweeted.
