Ireland's 4x200m Freestyle Relay have smashed the Irish senior record on day six of the World Swimming Championships in Gwangju, South Korea.
The quartet, swimming together as a relay for the first time, took over 16 seconds off the 2013 record of 7:30.45 to touch second in their heat and finish in 16th place overall in 7:13.91.
The team had a positive start with Jack McMillan leading off in a lifetime best of 1:48.00, his previous best had sat at 1:48.56.
Strong swims from Robbie Powell (1:48.84), Jordan Sloan (1:47.84) and Brendan Hyland (1:49.23) saw the team finish just under two seconds off the last Olympic qualification spot of 12th place, that was secured by Switzerland in 7:12.08.
The relay team is still in the running for a Tokyo 2020 place with four further spaces available for those ranked in the World Top 16 in May 2020.
Shane Ryan, Conor Ferguson and Niamh Coyne all return to the pool on Saturday, for the penultimate day of action in Gwangju.
Ryan and Ferguson compete in the 50m backstroke. while Coyne takes to the blocks in the 50m breaststroke.
Ryan will use the heats to prepare for the 4 x 100m Medley Relay on the final day of the meet, with the lead-off 100m backstroke leg for Ryan being both an opportunity to go under the Olympic qualification time individually and an important building block in aiding this team to a potential Tokyo place, should they be able to finish in the top 12.
In Dublin last night, at the Irish Summer National Championships, Larne's Danielle Hill regained her crown as the fastest ever Irish woman in the pool. Hill clocked 25.29 in the 50m Freestyle final knocking .13 off the previous record held by Mona McSharry (25.42) set at the World Youth Olympic Games in 2018.
