The Australian Short Course (25m) Nationals continued Friday at the South Australia Aquatic Centre in Marion, Adelaide.

Cate Campbell again stole the show, breaking the Commonwealth, Australian, and all-comers records in the 50m freestyle. 

Day Two Full Recap

LIVE RESULTS 

Campell's 23.19 smashes her previous best of 23.47 from way back in 2013 and is just 0.26 off Ranomi Kromowidjojo’s world record. With Campbell, Kromowidjojo, and Sarah Sjöström all set to go head-to-head at next month's three World Cup meets in Asia, this is another record certainly in danger.

1. 23.19 -- Cate Campbell (CR)
2. 24.01 -- Shayna Jack
3. 24.08 -- Bronte Campbell

National teamer Travis Mahoney and Japanese visitor Daiya Seto had two clashes on Friday night, splitting them at one apiece. Mahoney first got the wire-to-wire win in the 200m backstroke with a 1:52.54 — in range of his best time in an event he has not focused on in the last few years. Seto won the battle for second in a respectable 1:53.93, before backing up less than an hour later to dominate the Aussies in the 200m IM. His 1:53.33 defeated Mahoney by almost two full seconds, and scared the Australian all-comers record from 2009.

In women’s racing on Friday, Emily Seebohm won her fourth gold medal of the meet in the 100m backstroke. Seebohm had to come from behind at the last turn to swim over training partner and young gun Minna Atherton, who really attacked the race hard from the start. University of Sunshine Coast star Kaylee McKeown, the 200m back finalist from Budapest, Hungary, closed hard to finish third. Atherton and McKeown are just 17 and 16 years old, respectively.

Seebohm won her third gold of the meet earlier in the day in the timed finals of the 100m IM. She cruised to win in 1:00.21, well off her best of 57.97 but good enough for the gold medal. Seebohm's golds on Friday brought her career total to 26 at the Short Course National Championships. Amazingly, Seebohm is just 25 years old.

In other events, the USC Spartans' Mikkayla Sheridan got her first national title in a come-from-behind win over Madison Wilson in the 400m freestyle. Wilson, who was contesting this event at this level for the first time, shot out to a big two-second lead at the 100m mark, before Sheridan, who negative split the race, caught her at 350m and never looked back.

Sydney youngster Zachary Attard stepped up to the plate in the men’s 200m freestyle, after the late withdrawals of Kyle Chalmers, Daniel Smith, and David McKeon here in Adelaide.

Attard trailed in the race for all but the last stroke, in a huge comeback win over Jordan Merilees, formerly of North Carolina. While the winning time of 1:45.89 is not particularly fast, Attard showed great composure throughout the race to collect his first national title at just 18 years of age.

1. 1:45.89 -- Zachary Attard
2. 1:45.99 -- Jordan Merilees
3. 1:45.96 -- Joshua Parrish
