Third silver for Firth at IPC World Championships in Montreal

Bethany Firth

Bethany Firth secured her third silver medal at the IPC World Championships in Montreal as she took a big chunk off her 100m breaststroke personal best.

Firth's time of 1:18.74 improved her previous best by nearly two seconds.

The 17-year-old county Down woman finished behind Spain's London Paralympic champion Michelle Alonso Morales who clocked 1:17.63.

Firth also won silver in the 200m freestyle on Monday and the 100m backstroke on Wednesday.

The Seaforde teenager won the 100m backstroke gold at last year's Paralympics in London.

Friday's event is regarded as Firth's weakest but she produced a superb swim.

"It's just amazing," said a delighted Firth.

"I don't normally like swimming breaststroke but I'm so pleased."

Firth's earlier time of 1:20.50 in the heats had placed her third going into the final behind behind Morales and Great Britain's Nicole Lough.

The Northern Ireland woman produced the fastest reaction time off the block and at the 50m mark she was in second place just .09 of a second ahead of Lough in third.

But Firth was determined not to be beaten to the silver medal, touching over 1.5 seconds ahead of the bronze winner Lough who finished in 1:20.30.

Ireland's medal tally now stands at one gold, three silver and two bronze at these championships with Firth accounting for the three silver medals.

Ellen Keane will be the only Irish swimmer in action on Saturday morning in her final event of the championships, the 100m butterfly S9.

Keane, who has already won 100m breaststroke bronze, is the fifth fastest seed going into Monday's heats and should be confident of a final spot.

James Scully will swim a straight final in the S5 100m Freestyle at 23:58 BST.

Scully won 200m Freestyle bronze earlier this week.

Ireland's gold medal was won by Darragh McDonald is the S6 400m freestyle on Monday.
