A defiant Sally Pearson says she is yet to reach the peak of her powers as an athlete and wont rule out a push for the 2020 Olympic Games in Tokyo.But for now, Pearson says she is setting her sights on next years world championships and the 2018 Commonwealth Games on the Gold Coast as she comes to terms with being forced out of the Rio Olympics by injury.I know what type of athlete I am and what Im capable of as an athlete. I dont think Ive reached my peak yet. I think Im capable of a lot more, Pearson told reporters on Thursday.Im only 29, track and field athletes can go on for a bit longer.But at this stage Im only looking forward to 2018.Theres not many chances you get to run in a major championships 10 minutes up the road from your house. It will be pretty special.Pearson, the reigning Olympic 100m hurdles champion, would be 31 for the Commonwealth Games and 34 by the time of the Toyko Olympics.But she wont be going to Rio after suffering a tear to her right hamstring during training on Monday at her Gold Coast base - seven weeks and one day out from her first scheduled Games heat.The tear was small but significant, in a high-risk location near her tendon and Pearson said she immediately knew it would put her Olympic hopes in serious risk.It comes 12 months after she suffered a broken wrist and a torn calf in a Diamond League event in Rome, a traumatic set of injuries that made her consider retirement.But Pearson insists she wont throw in the towel after her latest setback.This is what I do, as a job, this is who I am. Im not just going to give up because I have an injury, Pearson said.This is a low time for me and it has been for a few years with different injuries, but Ive always bounced back, Ive always come back fitter, stronger and faster, and achieved amazing things still through adversity.Its unfortunate, these are the down times, but the highs always make up for it.Athletics Australia head coach Craig Hilliard said he was devastated for Pearson but believed she would bounce back and that the rest of the Australian team could have a successful campaign in Rio without her.Clearly her body is telling her it needs a rest from the sustained mental and physical workload needed to train and compete at the highest level, he said.However, I am confident that with appropriate rehabilitation and rest she can be back as strong as ever.

Its 1987 and a Brazilian playmaker, known as Mirandinha, is being paraded around St James Park to the passionate Newcastle fans.Martin Guptill smote 80 off 48 balls as New Zealand beat Pakistan by 22 runs to become the first side to reach the World Twenty20 semi-finals. The opener scored 48 per cent of his runs through the mid-on region, striking 10 fours and three sixes, to set the Black Caps on course for 180-5.Sharjeel Khan produced a dazzling 47 off 25 balls in response but the chase fizzled out as spinners Mitchell Santner (2-29) and Ish Sodhi (1-25) grasped control, Shahid Afridis side closing on 158-5. Martin Guptill targets his favourite area - going straight against Pakistan Guptill, the third highest run-scorer in T20I cricket, opened his boundary count in glorious style, launching Mohammad Irfan down the ground for a straight six before plundering three fours off the next over, bowled by Mohammad Amir.The right-hander dominated an opening stand of 62 with Kane Williamson (17), who was rather subdued before he miscued a drive off Irfan to Afridi at cover.Colin Munro, likewise, failed to get going - his switch-hit picking out Sharjeel in the deep off Afridis bowling - and Guptill might have fallen on 49 but survived a close lbw shout from the same bowler.Reprieved, he reached his 10th T20I fifty off 33 balls and scored at two-a--ball thereafter before playing Mohammad Sami on, attempting to dab the ball past third man.ddddddddddddCorey Anderson (21) fell displaying greater intent, mistiming a drive off Afridi to long-off, and Luke Ronchi steered Sami to point but Ross Taylor (36 not out off 23 balls) put New Zealand in the box-seat. Kane Williamson made 17 but failed to really get going Pakistans response was bullish - Sharjeel striking nine fours and a six as he and Ahmed Shehzad (30 off 32) racked up 65 off the first 5.3 overs.Khalid Latif, in danger of halting the flow, slogged Santner up in the air and Shehzad also fell to the left-arm spinner trying to force the rate.Fellow slow bowler Sodhi helped pile the pressure on Pakistan, picking up the key wicket of Afridi in the process - the skipper lofting the ball high to long-off where Anderson stretched to hold a stunning catch.With the required rate steadily mounting, Umar Akmal (24 off 26) and Shoaib Malik strived in vain to produce a grandstand finish but with no boundaries coming in the last 5.1 overs, New Zealand cantered home.Watch highlights of New Zealand against Pakistan on Sky Sports 2 from 7pm - then join us for England against Afghanistan live on the same channel from 9am on Wednesday.
