Much as I don't like these two picks, Matchroom is sticking to its rule that players have to participate in big WNT tournaments to be eligible for the Reyes/Mosconi. That rules out SVB, Filler and the Ko brothers. So MR had to scramble a bit.
Both the Reyes Cup and Mosconi Cup are based on the Ryder Cup golf event.
Although it is far less common now than in the past, there are/were players that play/played both the European golf tour and the PGA tour, whose tournaments regularly clashed in the schedule. Such players were always welcomed with open arms in PGA events, including the end of year Fed Ex Cup if they had accumulated enough points to qualify. Provided that they had played in fifteen events (about 50% of those held), they could even keep their PGA touring card provided that they maintained a Top 125 ranking.
For much of their respective careers, three of the greatest ever European golfers, Bernhard Langer, Nick Faldo, and Colin Montgomerie, played both golf tours, playing enough events on each to maintain touring pro status on both.
If we have a meaningful reconciliation between WPA and Matchroom, they must have the kind of working relationship that the European Tour and the PGA always maintained. I think that day is coming, but for now, there are some growing pains.
