Meronk, 30, was considered one of the favourites for a captain's pick especially having won three times since July 2022.
The giant Pole won the 2022 Irish Open, 2022 Australian Open and the 2023 Italian Open earlier this season, the latter of which was staged at this month's Ryder Cup venue Marco Simone Golf Club in Rome.
Meronk also had a number of stats seemingly in his favour ahead of the six picks.
He ranks third in the DP World Tour's Race to Dubai standings behind McIlroy and Rahm as it stands right now.
Meronk also leads the strokes-gained off the tee category on the DP World Tour, and he ranks second in strokes-gained total and fifth in scoring average.
Denmark's Nicolai Hojgaard, a player Telegraph Sport's James Corrigan took the mickey out of with a rather hilarious post, was seemingly given the nod over Meronk.
Sky Sports Golf's Jamie Spence, who knows Meronk well, texted GolfMagic this afternoon to say: "I am absolutely devastated for Adrian, he's played so well this season. It's such a shame for him and I know he will be hugely devastated to miss out. He should 100% be in the team and it's just hugely disappointing in all honesty."
“If (Meronk) doesn’t get (a RC pick) tomorrow, it will be the crime of the century.” Welp.— Pro Golf Critic (@ProGolfCritic) September 3, 2023

Mark Roe, who also works on Sky Sports Golf, yesterday claimed it would be "the crime of the century" if Donald did not pick him.
@AdrianMeronk not making the European Ryder Cup is a crime. He’s 3rd on the race to Dubai and he won on the course that hosting.— Paul Goydos (@PaulGoydosPGA) September 4, 2023
Former US Ryder Cup captain Paul Goydos also played the "crime card".
To Meronk's credit he took to Twitter four hours after the picks were made public by Donald with a short but sweet message for Team Europe.
Good luck @RyderCupEurope— Adrian Meronk (@AdrianMeronk) September 4, 2023
Meronk's golf coach Matthew Tipper also took to social media to reveal a bit more as to how his man was feeling this afternoon.
The PGA coach admitted the Meronk camp was "hurt" by the snub but that they will all be supporting the team and hoping they win the Ryder Cup back in Italy on October 1.
What do you make of Donald's six picks in the team? Should Meronk have received a pick, especially having won this year's Italian Open on the Ryder Cup course at Marco Simone? Share your thoughts and comments over on the GolfMagic social media channels.
