Young Dutchman Gian van Veen wins the Machineseeker European Championship in Dortmund.
The top 32 players on the 2025 European Tour rankings competed for the coveted title at Dortmund's Westfalenhalle.
Littler knew victory at the European Championship would guarantee him world No 1 spot for the first time but the teenager was upset by James Wade.
Humphries - the fifth seed in Dortmund - demolished Poland's Krzysztof Ratajski before overcoming Cameron Menzies in a last-leg decider. He defeated Wade to reach the final, but was stunned by Dutchman Van Veen in a thriller.

The top 32 players from the European Tour Rankings qualify for the European Championship.
The European Tour Rankings are based on prize money won in European Tour events, with 14 held across continental Europe over the season.
The qualification campaign ended after the German Darts Championship on October 19, where Nathan Aspinall celebrated his third European Tour title of the season and secured top spot in the standings.
Chris Dobey, Dave Chisnall and Cross all earned their spots after last week's final qualifying event in Germany, with Andrew Gilding, Joe Cullen and former world champion Michael Smith among those to miss out.
Ritchie Edhouse has also failed to qualify for this year's contest, 12 months from sensationally thrashing Jermaine Wattimena in the final to claim a maiden TV title as a 250/1 outsider.
Michael van Gerwen is a four-time champion but last lifted the trophy in 2017, his fourth consecutive victory at the event, while former world champion Rob Cross and Peter Wright are both two-time winners.
The European Championship is played over legs rather than sets, with the number required to win increasing as the rounds go on.
The first round is held across two sessions on Thursday and Friday evening, with all matches played over the best of 11 legs, before the second round takes place on Saturday and sees matches increased to best of 19 legs.
The quarter-finals take place on Sunday afternoon and is also a race to 10 legs, before the semi-finals and final on Sunday evening are played over a best of 21.
The next TV major live on SportNews is the Grand Slam of Darts in Wolverhampton from November 8-16, before the World Darts Championship runs from December 11-January 3 at the Alexandra Palace.
