Littler beat the tricky Rob Cross in his fourth-round match, after Luke Humphries and Michael van Gerwen had reached the last 16 the night previously.
Littler make light work of veteran Mensur Suljovic in the third round, and he continued his winning run against Cross, defeating the 17th seed 4-2.
But, earlier in the day, the 15th seed Nathan Aspinall was stunned at the third hurdle by Kevin Doets.
