Bryce Harper has been waiting all season for a signature moment with the Philadelphia Phillies.

It finally came on Thursday.

The $330 million outfielder slugged a dramatic walk-off grand slam to help the Phillies cap a thrilling 7-5 comeback victory against the Chicago Cubs.

Bryce Harper slugs walk-off slam

With the Phillies down two runs, Harper turned on a pitch from Derek Holland and sent a no-doubt missile into the second deck at Citizens Bank Park.

You wouldn’t know that, though, by Harper’s run around the bases. Like the baseball, he took off like he was shot out of a cannon and sprinted like he was going for an inside-the-park home run.

That’s what pure joy looks like.

It’s the moment Harper and the Phillies have been waiting for all season. And what a moment it was.

Thrilling comeback

The Phillies entered the ninth inning down 5-1, but chipped away as Chicago used three different pitchers in an attempt to record the final two outs. Holland was summoned specifically for Harper, but couldn’t put him away. The final pitch was a 95-mph heater right in Harper’s wheelhouse.

It took a team effort to reach that point, and that includes help from Chicago’s bullpen and defense.

Reliever Rowan Wick got one out, but couldn't finish the inning after César Hernández reached on an error and Scott Kingery and Brad Miller both singled. Cubs manager Joe Maddon brought in former closer Pedro Strop next, but he only added fuel to the fire by allowing a single to Roman Quinn and hitting Rhys Hoskins with a pitch. That loaded the bases and set the stage for Harper.

Harper’s parents left early?

There was still a pretty good gathering of fans who hung around hoping for a Phillies comeback.

Apparently, that group didn’t include Bryce Harper’s parents.

During his postgame interview, Harper indicated that his parents may have left early.

Considering that Harper was due up seventh, it might have felt like a safe bet that he wouldn’t bat again. If they actually did indeed leave early, Harper might never let them live it down.
