Day one of the Rio Olympics was a major disappointment for India, with below par performance from the shooting, tennis and the table tennis contingent. However, the men's hockey team have got off to a winning start, defeating Ireland, 3-2 in their opening match.

PR Sreejesh' men was the only saving grace for India in the opening day of the competition. VR Raghunath and Rupinder Pal Saingh were on target with their drag-flicking skills, which played a huge hand in helping their team emerge victorious.  

There were great hopes from shooter Jitu Rai, who had done well in many world events. But the Indian's performance in the 10m air pistol event was not enough, as he finished eighth in the finals of the competition. He was the first shooter in the finals to crash out, with a score of 78.7, which was utterly disappointing. But, Rai still has a chance to return home with a medal, as he is one of the strong contenders in the 50m pistol event.

Other shooters like Apurvi Chandela and Ayonika Paul came up with a disappointing result in the women's 10m air rifle event.

The much-talked about pairing of Leander Paes and Rohan Bopanna exited the competition in the first round itself, losing to Lukasz Kubot and Marcin Matkowski of Poland. The Indian pair lost the match in straight sets, score reading 6-4, 7-6 (8-6) in the match, which was over in 84 minutes.

The tennis team faced another setback, when the women's pair of Sania Mirza and Prarthana Thombare lost in the first round to China's Shuai Peng-Shuai Zhang, score reading 7-6, 5-7, 7-5. The Indian pair did give their best, but it was still not enough as the match lasted more than three hours. With this India's men's and women's doubles journey has comes to an end, and one will look forward to Sania and Bopanna to deliver in the mixed doubles competition.

Though India might not have been a huge force in the table tennis, it was disappointing when all the four paddlers – Soumyajit Ghosh, Mouma Das, Manika Batra and Sharath Kamal - lost in their respective first round matches. Their journey has come to an end, much earlier than anticipated. Weightlifter Mirabai Chanu also did not have a great day as she failed to impress after no lift in the clean and jerk event.

Rio Olympics might not have started on a good note for India, athletes in other sporting events will hope to come up with a better performance in the next few days.
