Mohammed Al Joaker and Khalid Kamali of the UAE both suffered early setbacks on the first day of the 2012 Dubai International Open last 16 stage at Dubai Snooker Club and by Tuesday night only one of them would be left standing.
Al Joaker went down 4-2 to Thai teenager Ratchayothin Yotharak, while Kamali lost 4-1 to young Indian Himanshu Jain in a low scoring, lacklustre match.
After the conclusion of the first round, Al Joaker and Kamali had won their respective groups and for this reason were drawn in the same Group N for the round robin, last 16 stage.
The UAE players were to face each other in their Group N encounter on Tuesday and the loser would be effectively left without a hope of qualifying for the knockout quarter-final which are to be played on Thursday.
Mohamed Shehab, the third UAE player to make it to the last 16 stage of the tournament, was the only one to stave off defeat as recovered from 3-1 down to edge past arch rival Mohsen Bukshaisha of Qatar 4-3 with the help of a break of 96 on Tuesday evening.
Al Joaker, a seasoned veteran with numerous international honours to his credit, started off well by capturing the first but could not continue the momentum and conceded three frames in a row to the 16-year-old Ratchayothin.
He recovered by bagging the fifth but Ratchayothin stood his ground well and took the close sixth frame to win the match.
There were oddities to be seen as well on the Day One of the last 16 round.
Pakistan's Mohammad Asif and Iranian Amir Sarkhosh took turns on Tuesday to light up the Dubai International Open stage with mesmerizing displays of potting but still both ended on the losing side.
Asif, despite going down 4-3 to compatriot Asjad Iqbal in his first Group P match, was easily the top performer of the day with breaks of 82, 107 and 120 points that gave him a 3-2 lead.
Asif had looked all set to clinch the match but a lucky pot paved the way for Iqbal to take the deciding seventh frame on the black.
Sarkhosh matched Asif's 120 in his match against Andy Lee of Hong Kong and his fate was no different as he also went down 4-2.
The last 16 stage, which starts on Tuesday, will also be a round robin affair with four groups of as many players each. The top two players from these groups will then make it to the knockout quarter-finals.
