Littler progresses as Van Gerwen and Smith exit Grand Slam of Darts
Littler got the evening off to an impressive start, narrowly missing out on his next TV nine-darter in his clash with Lourence Ilagan.
Nevertheless, the 17-year-old won 5-3 and thus secured an unbeaten group win.
The 17-year-old lost only one leg in the first two matches, an impressive form and that just before the PDC World Championship.
Gary Anderson had slight problems with Noah-Lynn van Leuven, but the Scot was ultimately able to triumph 5-2 after an interim 2-2.
Then there was a close fight between the Dutch youngsters. Once again, Wessel Nijman came out on the short end of the stick - despite a 108 average, he lost 5-4 and missed a nine-darter in his match against Gian van Veen.
Van Gerwen sensationally out
Jermaine Wattimena continued his run and narrowly won 5-4 against Austrian Mensur Suljovic.
Dimitri van den Bergh was then convincing. Keane Barry went down 5-1 against the Belgian and missed out on the knockout phase.
Michael van Gerwen let himself go and lost 5-4 to Ryan Joyce in a close match.
This is the first time in 13 years that the Dutchman has not reached the last 16 of the tournament.
Mike De Decker then showed Michael Smith once again why he is one of the hottest commodities on the tour at the moment.
With a 100 average and 5-0, there was nothing for the world champion to take despite four 180s.
The final match of the evening was played by Stephen Bunting, who defeated Josh Rock 5-2.
