Although she surrendered her overall lead, Brianne Theisen-Eaton improved her chances of victory in the pentathlon after throwing a big season’s best in the shot.
The Canadian improved with each round, throwing 13.44m, 13.60m and 13.70m to put her on course to exceed 4800 points and perhaps even break the North American record.
Although Alina Fodorova produced the best mark of the day with 15.44m, it was more than half a metre down on her best; the Ukrainian would have been hoping to bank even more points in this event.
Teammate Anastasiya Mokhnyuk produced an indoor PB of 15.01m, which was enough to move into the overall lead. Fodorova is just eight points behind in second place with Theisen-Eaton a further 64 points adrift.
USA’s Barbara Nwaba moved into medal contention after setting an outright PB of 15.00m. Hungary’s Gyorgyi Zsivoczky-Farkas moved up one place in the overall standings after throwing 14.54m.
NCAA indoor pentathlon champion Kendell Williams came within 10 centimetres of her recent PB with 13.45m, but her second throw landed wide of the sector and hit a photographer.
