Michael van Gerwen had to overcome an opponent in record-breaking form to reach the last 16 of the PDC World Darts Championship, beating Cristo Reyes 4-2.
The former champion was heavy favourite to beat the Spanish 32nd seed but was made to fight hard for the win.
Reyes pulled level at 1-1 to show he was not going to roll over for Van Gerwen and looked capable of pulling off what would have been a huge upset at Alexandra Palace.
Van Gerwen held his nerve to come away with the win, but Reyes did finish with a piece of history - his average of 106.07 was the highest for a losing player at the World Championship.
Raymond van Barneveld faced no such problem as he thrashed Alan Norris in straight sets to set up a clash with Adrian Lewis.
In front of a raucous crowd, the Dutchman romped to victory - winning the first 10 legs before Norris eventually got on the board.
It only delayed the inevitable, though, Van Barneveld finishing with an average of 103.59 to stroll into the next round.
Sixteen-time champion Phil Taylor was not at his best but escaped with a 4-0 victory after Kevin Painter failed to take his chances.
Earlier in the day, seventh seed Dave Chisnall ousted Chris Dobey 4-2, while there were wins for Mark Webster and Daryl Gurney.
