In the last event of the night in Budapest, Russian Kliment Kolesnikov broke the world junior record with a 53.38 in a swim-off for first alternate in the 100 back. Kolesnikov lowered his own world junior record that was a 53.65 from July 2016.
Kolesnikov beat China’s Li Guangyuan who was a 53.70. The two tied for ninth at 53.84. Kolesnikov won’t swim in tomorrow’s final but his 53.38 would have been seventh in the semi-finals. Kolesnikov is just 17 years old so he has another year to lower his world junior record.
