National champion makes finals
The 29-year-old national kegler, who ended a three year title drought with a victory in the Singapore National Championship last month, posted 214, 212, 241, 171, 174 and 243 for a total of 1255 to finish 13th in the squad.
But Lee's earlier effort of 1298 put him in 19th position in the overall standings and crucially securing his spot in the Stage 1 finals.
Singapore's Jason Yeong-Nathan and Lionel Lim made little headway as the duo shot 1190 and 1159 in Squad 8. Jason occupied 56th position while Lim ended in a lowly 75th position.
Hussain Al-Suwaidi is the new leader to dislodge his fellow compatriot and Asian Indoor Games triple gld medalist, Naif Oqab. Ong is third while Day 1 high series award winner, SHaker Al-Hassan dropped to fourth.
Seven more squads are scheduled for the next two remaining days of qualifying - three on Wednesday and four on Thursday. A one-game desperado squad will be held after the last squad to give bowlers a final chance to make the Stage 1 finals.
