Despite a good start, Bangladesh golfer Siddikur Rahman slipped to the back nine as he teed off his 2016 Rio Olympics campaign with a tied 56th position in the opening round of the men's individual golf event at Olympic Golf Course in Brazil on Thursday.
Siddikur, the first ever Bangladeshi to qualify for the Olympics directly, began his second round mission on Friday with the aim of rectifying the mistakes from the opening day.
The 31-year old carded four-over-per 75 to finish the first round above only four participants out of 60. Although the two-time Asian Tour winner started his front nine well scoring two birdies on the fifth and eighth holes, he stumbled in the back nine where he struck five bogeys.
Meanwhile, Bangladesh swimmer Mahfizur Rahman Sagor made his second Olympics appearance as he finished 54th among 85 participants in the heat of the men's 50-metre freestyle event.
The 23-year old swimmer however, kept his promise by recording his best ever personal timing. Sagor clocked 23.92 seconds on Thursday. His previous best was 23.93 seconds which he recorded in an open swimming competition in Thailand this year.
The opponents proved to be a bridge too far for the man from Pabna, whose best ever timing was only good enough to earn him fifth position in heat number five. He was subsequently ruled out in the preliminary round.
Earlier on Wednesday, Shyamoli Roy failed to qualify from the round of 32 in the recurve bow event after the 22-year old archer lost in straight sets against Gabriela Bayardo of Mexico.
The fastest man of the country, Mezbah Ahmed, will begin his Olympics campaign on Saturday at 6:30pm in the men's 100m freestyle heat.
Meanwhile, athlete Shirin Akter was eliminated from the Rio Olympics after Bangladesh's fastest woman finished fifth in the heats of the women's 100m event on Friday.
