Backstroke specialist Corey Main has made an important career breakthrough by qualifying for a final at the swimming world championships in Budapest.
New Zealand 22-year-old Main secured the eighth and final spot for the men's 100m final on Tuesday after two strong swims.
Main was ninth fastest in the morning heats with a personal best time of 53.97 seconds. He lowered that again in the semi-finals with 53.76sec, storming home with an impressive second length of 27.54sec.
Florida-based Main has made regular appearances in 100m and 200m semi-finals at major international meets - including the 2015 world championships and last year's Rio Olympics - but had routinely failed to advance to the last eight.
Olympic silver medallist Xu Jiayu dominated both sessions, clocking a slick 52.44sec in the semi-finals.
