Reigning champion Michael van Gerwen suffered a shock first-round exit at the Betfred World Matchplay in Blackpool, losing 10-7 to Brendan Dolan.

Three-time winner Van Gerwen could not have made a worst start to his title defence as world number 27 Dolan won the first three legs on his way to a 4-1 lead at the break.

Van Gerwen dug deep to level the scores at 5-5, aided by a 137-finish, but Dolan reasserted control to forge 9-6 ahead and although the world number three pulled it back to 9-7, the Northern Irishman was not to be denied.

"Brilliant feeling!"

World number one Michael Smith cruised through to the second round, but was far from his best as he beat Steve Beaton 10-2.

Smith hit the bull for a huge 161-finish on his way to a 4-1 lead and opened up an 8-2 advantage with the help of two more 100-plus checkouts before comfortably seeing the match out.

Luke Humphries produced another impressive display at the Winter Gardens as he stormed into the second round with a 10-2 win over Portugal’s Jose de Sousa.

World number six Humphries, who produced a 114-finish to open up an 8-1 lead, averaged 101.78 over the 12 legs.

BULLY BOY UP AND RUNNING!

It's not the start Michael Smith will have wanted, but it's a winning start and that's all that matters!

The World Champion comfortably defeats Steve Beaton 10-2 to advance to round two…
