Kay lost his first two games but returned strongly to ease past Justin Smith (4-1) and whitewash Fallon Sherrock 4-0 with a 95.5 average as he looks to have a solid campaign.
Sherrock herself had started the day great seeing off Boris Koltsov once again in a deciding leg with the Russian's doubles proving the deciding factor missing three match darts allowing 'The Queen of the Palace' a route through.
Paul Nicholson who was denied by Martin Adams to begin the week has started well seeing off Justin Smith 4-2 with a high checkout of 112.
But at the moment Smith, Koltsov and Mike Warburton are all locked on four points alongside Kay so it is still very much up for grabs.
Martin Adams has been the runaway leader this week but has only played once so far losing 4-1 to Warburton to begin his day, can he make it a clean sweep later today?
There will be 21 games a day which will be best of 7 legs. Pool A will take part on Monday, Wednesday and Friday. It begins everyday as a result at 10:30 am running till 5:30 pm and sees live action continue for four more weeks than initially planned.
The scores are recorded during matches via a webcam with this then uploaded to various scoring services and bookmakers who are all showing the action. The livestream is provided by organiser MODUS .
