Freddie Flintoff, who is new to the Sky Sports commentary team for the NatWest T20 Blast, was left stunned when Jason Roy advanced down the pitch and smashed David Wiese for six.
A shot that was so big, it eventually went out of the ground.
Earlier in the summer, Roy was desperately out of form, and was eventually dropped by England in the Champions Trophy.
Yet, he has performed well so far in this season's T20 Blast, and having hit 50 off 33 balls, he looks back to his best and is sending out a strong signal to the England selectors.
Roy's half century, along with Aaron Finch's outstanding century, helped Surrey to their fifth win of the season to put them in strong contention to head to into the quarter finals.
Surrey overcame Sussex, who hit 176 in reply, meaning they eventually lost by 17 runs.
Roy and Finch have been one of the standout opening partnerships in this year's tournament and both made big runs. Yet, Finch was named Man of the Match after a memorable 114 not out from just 64 balls, which included 14 boundaries.
You can see Roy's massive six in the video below, but make sure you have the volume on, as you won't want to miss Flintoff's reaction.
Quite an unbelievable shot, and quite an unbelievable piece of commentary from Flintoff.
Finch told BBC Radio London: "Between Jason and I we’ve got the team into some good positions but then probably let the middle order down by not being there at the end.
"So it was nice for one of us to go through. The middle of the innings was a bit frustrating and we just had to bide our time for one big over and thankfully it came."
Yet, for Roy, he will be targeting a return to the top of the order for England in both one day internationals and T20 fixtures later this summer against the West Indies.
Surrey will next return to the Oval on Thursday to take on Gloucestershire, they are currently in sixth position in the South Group and so will be looking for a strong finish to give them a chance of progressing through to the quarter final stage.
