Mensur Suljovic got the retention of his HappyBet International Darts Open title off to the perfect start as he beat William O'Connor 6-3 at the SACHSENarena in Riesa, Germany.
The 45-year-old, who clinched his first ever TV title at the Unibet Champions League of Darts last weekend, yet again proved his class as he averaged 102.32 on his way to victory.
Suljovic started where he left off in Cardiff as he clinched the opening two legs, before quickly being pegged back by the Irishman.
But the Austrian's superior quality quickly shone through as he clinched three legs in succession, including a match-high 84 checkout on his way to victory.
Rob Cross, who reached the final of the German Darts Grand Prix earlier this month, was sent packing at the hands of youngster Josh Payne in a 6-4 defeat.
The 27-year-old has enjoyed an electric start to his PDC career, but saw his spark extinguished by Payne as he broke Cross' throw twice in three legs to clinch victory.
Another in-form player who fell at the first hurdle was Daryl Gurney as he succumbed to a 6-5 defeat to Dennis Nilsson.
The Swede, who once finished runner-up in Sweden's Strongest Man, showed superb form on the doubles - landing 60 per cent of his efforts as he continued a dream debut on the European Tour.
Michael Smith was the third seed to crash out of the evening session as he lost 6-3 to Ron Meulenkamp.
Recently becoming a father for the second time, the 27-year-old laboured in a disappointment display, and despite having an eight point advantage in the averages, was made to pay by the Dutchman for costly misses at the doubles.
Alan Norris was in imperious form as he averaged 105.06 to silence the home crowd and send Max Hopp packing.
After losing the opening leg, a brilliant display of finishing saw him clinch six legs in succession to secure a Third Round berth.
Simon Whitlock also showed neat touch as he averaged just over the 100 mark to edge out compatriot Kyle Anderson 6-4.
Trailing 4-2, Whitlock held his nerve on the doubles by landing two-thirds of his attempts to put together four straight legs and move into the next round.
Elsewhere, Peter Wright comfortably saw off Chris Quantock 6-2, whilst Dave Chisnall beat Darren Webster 6-4.
Earlier in the day, Joe Cullen put in the performance of the competition so far as he averaged 113.77 in a thumping victory over Richie corner.
Impressive on the doubles too, the 28-year-old took out checkouts of 116 and 147 as he quickly raced to the finish line.
It was a great day for the Huybrechts brothers. Averaging just under 100, Kim was clinical on the doubles as he brushed aside Christian Kist.
Brother Ronny faced a sterner test in seeded Spaniard Cristo Reyes but also progressed with a 6-4 victory.
Another seed to fall was young Dutchman Benito van de Pas, as Peter Jacques landed six out of 10 attempts on the doubles to clinch a 6-2 win.
In the opening game of the day, Gerwyn Price landed the highest checkout of the Second Round as he took out 167 on his way to a 6-4 victory over Steve Lennon.
Jelle Klaasen posted his highest average (97.13) since wrist surgery earlier in the year as he beat Ireland's Brendan Dolan 6-4.
Meanwhile, there were victories for Ian White and Mervyn King as they Keegan Brown and John Michael 6-3 and 6-2 respectively.
The HappyBet International Darts Open continues on Sunday with the third round in the afternoon, before the Quarter-Finals, Semi-Finals and Final in the evening.
