Kyron Duke and Kirsty Taylor set new Para-athletics world records
Kyron Duke set a new F41 shot put world record of 14.19m at the Bayer Invitational in Leverkusen, Germany.
Fellow Welsh athlete Kirsty Taylor, 19, also set a new world mark in the T44 long jump with a distance of 4.52m.
Two-time world silver medallist Duke, 26, is in fine form this season, having thrown 14.53m - an unofficial record - in April in Leira, Portugal.
Duke is now the favourite to claim a first World Para-athletics title in Dubai, UAE, next November.
"It's amazing. I've known I've been able to do it for a long time," said Duke.
"It's just to get it ratified now and it will be there for everyone to see, and a good start to go in to the Worlds in November.
"I know what I can do, I know my plan with all my coaches, we've just got to get everything right for the day."
