World number three Peter Wright was dumped out of the PDC World Darts Championship on Sunday night as Toni Alcinas pulled off a surprise 3-1 triumph.

The Spaniard took the first two sets against Scotland's Wright, who was dressed in a Santa Claus themed outfit, and the 2014 finalist promptly pulled a set back.

But Wright found himself throwing to survive in the fourth set, which Alcinas won 3-2 before celebrating enthusiastically at Alexandra Palace.

Luke Humphries set up a second-round clash with Stephen Bunting by reeling off nine consecutive legs - including five 180s - to triumph 3-0 inside 20 minutes.

Newbury-born Humphries, 23, said afterwards: "If it weren't for the development tour I wouldn't be doing this."

Darius Labanauskas became the first ever Lithuanian to reach the second round after completing a 3-1 victory against Matthew Edgar.

Singapore's Paul Lim, making his 23rd appearance in the competition, could not cope with Ross Smith as the Kent hopeful turned on the style with a 138 checkout during his dominant 3-1 victory.

Earlier, Dave Chisnall fought back from two sets down to beat Josh Payne and reach the third round.

Payne took the first two sets without dropping a leg but Chisnall broke him and then forced a decider.

Chisnall told pdc.tv: "I just had to believe that he wouldn't be able to keep playing as well as he was and I know that I get better the longer games go on."

Elsewhere in the morning session, Brendan Dolan defeated Yuanjun Liu of China 3-0, Germany's Gabriel Clemens beat Aden Kirk in straight sets and William O'Connor dispatched Yordi Meeuwisse, also to nil.

Monday will see Labanauskas face four-time world champion Raymond Van Barneveld while Anastasia Dobromyslova is in action against Ryan Joyce in another eye-catching tie.
