Adam Peaty sent out the strongest signal yet he'll be the one to beat at this year's World Championships in Russia as he clocked a season's best to take the 100m Breaststroke title at the International Swim Meet in Berlin.
The 20-year old City of Derby swimmer - who landed the Commonwealth and European titles over 100m Breaststroke in 2014 - took the touch in 59.04 to strengthen his position at the top of this year's world rankings.
Peaty's time was the fourth fastest of his career and his fastest time away from a major summer championships.
Peaty also claimed the 200m Breaststroke crown in Berlin in 2:14.58 while City of Manchester's Chris Steeples took 100m Breast silver behind Peaty in 1:00.92 - the third fastest time of his career.
Jessica Fullalove was also impressive over the opening two days in Germany, claiming 100m Backstroke gold and 200m Backstroke silver with her fastest times since the 2013 British Swimming Championships.
The 18-year old clocked the second fastest time of her career with a 1:00.82 effort over 100m, having gone 2:11.63 over 200m on Friday night.
Among the other British medallists, City of Derby's Danielle Lowe took 400m Individual Medley gold, City of Manchester's Sam Horrocks doubled up with 50m Butterfly bronze and 100m Butterfly silver and Manchester's Rebecca Guy won a gold (50m Free) and two silvers (50m Fly, 200m Free).
