A leg later, he became the first to keep his own leg and in the fourth leg, the Welshman emulated him.
A fifth leg - started by Dolan - had to bring a decision. Dolan threw out his second 100+ finish by finishing 144 to take the first set.
In the second leg of the second set, Price threw the first 180 of the match and missed two darts on the double for a break, allowing Dolan to move to 1-1.

In Dolan's leg, Price was on 86 after nine arrows, saw Dolan miss an arrow to win the leg and won the second set.

Pietreczko grabbed a break and a 2-0 lead in the second leg of the fourth set and was allowed to start the third leg himself to move to 3-1 in sets. He had no problems in that leg and won the set in style by throwing out 121.
Double 16 from Humphries
Pietreczko won his sixth consecutive leg and led by a break in the first leg of the fifth set. A downcast Humphries threw his second 180 of the match in the second leg and broke back to 1-1. Humphries missed the double 16 - on which he was 1-for-11 at the time - and Pietreczko kept his own leg and got to match point. Humphries was allowed to start the fifth leg and took the set by now hitting the double 16.
Humphries needed a break sometime in the sixth set and he did so in the third leg for a 2-1 lead. He then kept his own leg and levelled the match.
By winning his own first leg, Humphries regained the lead for the first time since the third set. From 87, he grabbed a break in the second leg and even reached match point. The Englishman threw his sixth 180 of the match and took the lead from 120.
He missed his first match dart and failed to finish 161. The second match dart was a hit for Cool Hand Luke, who turned the match completely around.

Gurney made it 2-0 in legs in the fourth set via a break but was broken back by Evans in the third leg from 100. A leg later, Evans equalised from 72 and Gurney was allowed to start the fifth leg.
