Daniel Wiffen booked his place in the 800m freestyle final at the World Aquatics Championship in Doha after finishing second in his semi-final. The 22-year-old was back in action after finishing seventh in the 400m freestyle final and clocked a time of 7.46.90 to finish runner-up to Italian Luca de Tulio, whose pace of 7.46.52 was the fastest of both semi-finals. The Armagh star will be back in the pool on Wednesday in what promises to be an extremely competitive 800m final, with less than two seconds separating de Tulio and the slowest qualifier.

While Wiffen qualified comfortably in the end, he still had some work to do with 100m or so left in the race to make sure he qualified for tomorrow’s final in Doha. “I knew it was going to be tight. I knew exactly what pace they were going, so I was like ‘I don’t want to leave it to chance coming fourth in the heat,’ so top two is what we wanted. “I’m looking forward to it (the final)… It’s going to be a great race.” Get the latest sports headlines straight to your inbox by signing up for free email alerts.
