Mona McSharry claimed bronze in the 100m breaststroke final at the World Short Course Swimming Championships in Abu Dhabi.
The Sligo swimmer powered to third in a new Irish record time of 1:03.92.
It caps a great week for McSharry, based at the University of Tennessee, who set a new Irish record of 29.59 in the 50m breasttroke final on Friday, but was just pipped for bronze there by Sweden's Sophie Hansson.
Tang Quinting of China took 100m gold in 1:03.47, with Hansson again in silver, in a time of 1:03.50.
"I was definitely nervous going into it because I knew I had the potential to medal and it's really nice to see that all come together in a race," she said afterwards.
"It felt really good and I’m glad I dropped time too.
"It’s been amazing. It’s been really enjoyable to watch other team-mates swim really well and have a great time.
"This is the first time we’ve gotten together as a group since the Olympics and it’s much of the same swimmers, and it’s just really nice to be able to have fun and compete together and be up against the best in the world."
It adds to the bronze medal won at the 2019 LEN European Short Course Swimming Championships in the 50m breaststroke.
It's Ireland's second medal of the championships after Ellen Walsh won silver in the 400m individual medley.
Walshe and Daniel Wiffen broke national records as they progressed at the World Short Course Swimming Championships in Abu Dhabi, while Jack McMillan advanced to tomorrow's 100m freestyle final.
Tokyo 2020 Olympian Wiffen set two new Irish records on Monday as he made it through to the 1500m final in sixth place.
Wiffen lowered a record he set in October again to 14:32.13 to finish fourth in his heat and sixth overall, earning a spot in Tuesday’s final.
During his 1500m, he also broke his own Irish record for 800m, reaching that point in 7:41.82 to lower the record by five seconds.
"It’s unbelievable," he said. "That was my goal for this meet, to make the final, and I’m not even in last, I’m in sixth, so I’m not even in the outside lane, which is going to be good. And I got a massive PB as well.
Wiffen's 1500m freestyle final is on Tuesday afternoon.
400m individual medley silver medallist Ellen Walshe put in two record-breaking swims in the 200m individual medley and 100m butterfly heats.
In the 200m individual medley heats Walshe dropped three seconds from her own lifetime best and two seconds from the national record set by Niamh Kilgallen in 2017 when clocking 2:08.69.
The Dubliner finished in ninth place, missing out on a place in the final by 0.09.
In the 100m butterfly heats Walshe bettered her own Irish record of 58.51 when swimming 57.32.
In her semi-final, a sixth-place finish in a time of 56.68 was not enough to progress to the final. Walshe missed out on the final by six hundredths of a second and was classified ninth overall.
Jack McMillan, who was part of the quartet that finished sixth in the Men’s 4x200m freestyle relay final on Sunday, will take his place in tomorrow's 100m freestyle final.
The National Centre Ulster swimmer clocked 47.04 in his heat to finish ninth overall, before going faster in his semi-final.
McMillan powered home over the last 25m in a time of 46.70 to earn eighth spot in Tuesday's final.
Fellow Tokyo 2020 Olympian Danielle Hill signed off her year with 24.83 to finish 22nd in the 50m freestyle heats.
She competed in four events in Abu Dhabi, getting through to the semi-finals in 50m backstroke on Sunday, where she finished 14th.
Ireland has now set 16 new national records in Abu Dhabi with one day left of racing.
On the final day of competition, Irish representation will be provided by Daniel Wiffen (1500m freestyle) and Jack McMillan (100m freestyle) in finals, with Niamh Coyne and Mona McSharry set to compete in the 200m breaststroke heats in the morning as well.
