Who will make it through to face Michael van Gerwen in the final?

It's another huge clash - a repeat of the World Championship final - as Luke Littler takes on Luke Humphries.

Since Humphries won at Ally Pally, Littler has won the last two meetings between the two, including in quarter-finals in Cardiff last week.

A fine fightback from Michael Smith but it proves to be in vain. It won't be back-to-back Premier League wins for Bully Boy.
