After De Sousa took an early 2-1 lead, it was Van Gerwen who took control. He took a 4-2 lead and seemed to be heading for victory in a straight line. But the Dutchman then missed some chances on the doubles, which allowed the Portuguese to come back to 4-4.
Van Gerwen ran out to an 8-5 lead and could almost feel a place in the quarterfinals. Still, De Sousa got a handful of chances to make it 8-8 again. He eventually found the double two to level the score again. After both men kept their own lay, a nineteenth and decisive lay had to be used. Van Gerwen managed to squeeze out a good leg, allowing him to qualify for the quarter-finals of the UK Open for the sixth time in his career: 10-9.
The tournament is over for Martijn Kleermaker. Opponent Luke Humphries quickly took a 3-0 lead, but saw Kleermaker come back to 3-3. Unfortunately, the Dutchman could not break any more after that. He only managed to win one leg and saw Humphries book a 10-4 victory.
On the main stage, there was a surprise defeat for Jonny Clayton. The winner of The Masters, who was in good shape again during this tournament, went hard against Krzysztof Ratajski: 10-3. On the same podium Dave Chisnall won after a nice match 10-8 against Alan Soutar and Gerwyn Price managed to book a big 10-5 victory over Chris Dobey, who missed the double twelve on the way for a nine-darter.
On the second stage, Simon Whitlock and Brendan Dolan fought out a beautiful fight. Dolan quickly took a 4-0 lead, but just like in his previous match, it was Whitlock who turned out to be the best in a decisive nineteenth leg: 10-9. Devon Petersen and James Wade also managed to conquer a place in the last eight: Petersen was too strong for Peter Jacques with 10-4, while Wade managed to take a fine 10-5 victory over Gabriel Clemens.
