World Number Three Jon Rahm hailed the JP McManus Pro-Am as "special and unique" as he returned to a country that holds fond memories for him.
The Spaniard claimed his maiden DP World Tour title at Portstewart Golf Club in 2017 before becoming a two-time Irish Open winner at Lahinch Golf Club two years later.
And he has enjoyed being back in Ireland for this week's charity fundraising event, which has seen many of the world's best players and some big-name celebrities descend on Adare Manor Hotel & Golf Resort.
The County Limerick venue, which will host the 2027 Ryder Cup, has earned glowing reviews from the players this week and Rahm was the latest star to pay tribute to both Adare Manor and the McManus family.
He said: "I can't really say enough nice things about the venue, about JP, and about the event they have put together.
"The best way I can describe it is that it's special and unique. Only a unique venue and a unique individual and a unique family like the McManus family can bring so many top golfers together for a charity event like this and make us have such a good time.
"We feel it, the crowd out there feels it and it's what makes it so special.
"A lot of us didn't know the magnitude. I had no idea there would be spectators. I had no idea there would be TV cameras.
"A lot of us thought it was a pro-am where if we were out of the hole we could just pick up and go to the next. We didn't realise how serious it was until Saturday afternoon, at least my case.

"So had to change a little bit of the mentality I had, but still here to have the best time we can and try to make it as enjoyable for the amateur partners and for the spectators out there."
Also in the star-studded field for the 36-hole pro-am is 15-time Major Champion Tiger Woods, who sent the bumper crowds wild in Monday's first round with a chip-in eagle on the 12th.
Woods also heaped praise on JP McManus, saying: "We know how much JP means to golf and what he's done for our sport and any time we can help out any which way we possibly can, we do and this is one of the ways we can pay tribute to JP and what he's done."
Xander Schauffele followed up Monday's sensational 64 with a 70 on Tuesday to win the tournament by one shot.
