As Bryce Harper got ready to hit in the top of the 5th inning Wednesday night at Wrigley Field, viewers were treated to another episode of “Storytime with Sut.”

Former Cubs Cy Young winner and current Marquee Sports Network analyst Rick Sutcliffe shared a hilarious story of the time he pranked Jon “Boog” Sciambi…with Harper’s help.

As the story goes, Sutcliffe and Sciambi were doing an ESPN broadcast of a Nationals game years ago and they noticed Harper had something written on the bottom of the knob of his bat. They speculated about what it might be, but didn’t come up with any concrete answers.

Fast forward to the next Nationals game the pairing did (April 11, 2017) and Sutcliffe had a prank already ready to go in his mind. He went up to Harper and asked if the star outfielder would write his name — “Sut” — on the bottom of his knob.

Sure enough, Sciambi also approached Harper before the game and asked, “what do you have on the bottom of your bat?”

Harper played along with Sutcliffe’s prank and said, “eh, just sometimes I’ll put a sticker or something.”

So when it came time for Harper’s first at-bat in the game, Sciambi noticed what was really on the bottom of Harper’s bat:

“I don’t believe that. Does it really say, ‘Sut’?” Sciambi asked on the April 2017 broadcast. “Is that Photoshopped?”
