The 25-year-old finished fourth overall in the opening event of the competition – the 60m hurdles – after coming fifth in her heat with a time of 8.23.
O’Connor, who also won silver at the World Championships in Tokyo in 2025, cleared 1.81m after two failures in the high jump as she tied for third overall before posting a personal best 14.70m in the shot put.
The Newry native was on 2909 points after three events, with Dokter leading the standings on 2943 points and Hall in second on 2926 points.
Dokter further extended her lead in the long jump, while a leap of 6.38m moved O’Connor into second position in the overall standings and onto 3878 points.
In the 800m, she finished second and recorded a personal best but finished third overall after Hall won the race with an impressive time of 2:06:32 to leapfrog O’Connor and seal the silver medal.
“I opened my season at my national championships a couple of weeks ago and since then I’ve had a little bit of up and down with training and had a few health issues,” O’Connor added.
“Coming here, I wanted five PBs and started off with the hurdles a little slower than I would have liked. That rolled into the high jump being a little sub-par, picked it back up with the shot [putt] and I was happy with that; long jump a little bit rocky with fouling on my first jump but I managed to get a decent jump in with my last attempt.
“I went out there in the 800 [metres] and tried my best. I knew it would be a hard ask, but I left everything out there and when I reflect later, I will be delighted with myself.
“I competed really well and I’m leaving here injury-free, so I’m looking forward to getting back and continuing building, but I have another medal to add to my collection, so can I complain? No.”
