Zach Miller has had an amazing week. 

The Chicago Bears tight end was re-signed to a remarkable one-year contract following a devastating injury, then two days later got to throw the first pitch at the Cubs-Phillies game Wednesday night. 

On top of that, his view of Jason Heyward's game-ending grand slam couldn't have been better. 

"Unbelievable night @Cubs," he wrote on Twitter with a video of the epic moment.

Heyward hit a game-ending grand slam off Adam Morgan to give the Chicago Cubs a 7-5 victory over the Philadelphia Phillies on Wednesday night.

Heyward's drive sent the Cubs to their eighth win in 10 games, and it came after Philadelphia's Dylan Cozens hit a tiebreaking, two-run homer against closer Brandon Morrow in the top half.

As he crossed home plate, teammates mobbed him.

"I was trying to keep it simple, one pitch at a time, try to make adjustments on the fly and that's easier said than done," he said. "I got a pitch to hit there and didn't miss it."

The grand slam was the third of his career and first since he knocked one out Sept. 30, 2015, for St. Louis at Pittsburgh. It was also the first extra-base hit against a lefty this season for Heyward, who previously had five singles in 36 at-bats.

"With something like this, hopefully it really generates some confidence," Cubs manager Joe Maddon said.
