But the fairytale ended for Clark and his men when Tasker drew almost on the verge of the ditch to pip the Orewa shot bowl and despite some frantic drives it couldn't be removed.
While a loss would not have ended Belliss' tournament, with three rounds today, it could have been a blow psychologically and it was a relieved Belliss who later admitted: "We were lucky to get out of it."
In the women's fours there were two upsets. Sandra Keith lost to a Mairangi Bay four skipped by Colleen Griffith and accomplished Auckland bowler Karen Hema, with national singles champion Leigh Griffin at three, lost to a little known Glendowie four skipped by Bev Cassie.
Birkenhead's Carole Frederick, who has Ruth Lynch and Lisa Helmling with her from the four which won the national title in 2012, lost her first two games, but to tough opposition, Anne Bateman, from Northland, and Orewa's Ann Pearce. Frederick did win her third game, though, and could yet qualify.
Women's skips in top form included leading contenders Karen de Jongh and Mandy Boyd and most of the favoured men, including Gary Lawson and Rob Ashton, ended the day unbeaten.
Especially impressive was a four skipped by Wellington's Raymond Martin which scored three comfortable wins.
