Ross Smith believes ‘karma will come around’ for Mensur Suljovic after his opponent encouraged boos from the crowd.Suljovic was also seen cheering Smith missing a match dart before going on to reach the Swiss Darts Trophy quarter-finals.Suljovic egged on the booing fans in the crowd before Smith missed a match dart at the Swiss Darts Trophy on SundayPDCAs the Englishman, who won the World Series of Darts last month, stepped up to try and hit double 18 to secure a victory, his rival stood behind him whipping up the crowd.Just before he threw his dart, Suljovic waved his arms in the air, gesturing for those booing to increase the volume. Suljovic then celebrated Smith missing, with commentators saying at the time: “I don’t think Mensur has covered himself in glory there.“He’s a master of the mind games but when your opponent’s on a match-winning double, to do that, is a little bit naughty.”The Austrian went on to back up his early celebration by going on to take out 55 and win the match to reach the quarters.He ran off celebrating wildly after landing the match dart, holding his fists aloft and roaring towards the crowd.Meanwhile, Smith looked disappointed and slumped off stage, seemingly finding out about Suljovic’s actions post-match, having not noticed what was going on behind him at the time.What has Smith said on Suljovic’s antics?“I don’t blame Mensur for me losing that game,” Smith wrote on X on Sunday afternoon. “I missed 2 match darts. Simple as that.“Obviously it’s impossible for me to know what he’s doing behind my back when I’m throwing, apart from the crowd’s response.“If he wants to be an absolute helmet, that’s on him. Karma will come around.”View Tweet: https://t.co/Dogi6ykEH5Suljovic gestured to the crowd to keep booing Smith before celebrating after his rival missed his throw at a doublePDCThe Austrian then ran off shouting in celebration when he stepped up to win the match and reach the quarter-finalsPDCDarts fans fume at ‘disgraceful’ SuljovicSmith was clearly not happy with Suljovic’s antics, even if he admitted that he was beaten by his own misses.And darts fans have also been making their thoughts known on social media, criticising the Austrian for his actions.One person wrote: “That was disgraceful.”Another posted: “Awful sportsmanship from Mensur.”“Why does the PDC allow such blatant cheating?” a third said.This is not the first time that Suljovic has been accused of cheating during a match, with Joe Cullen calling him out last year.
