Janine Belton was today sweating on her chance of near-guaranteed medal glory.
The Bradford swimmer will find out just hours before tonight's relay final whether she will make the team.
Despite winning gold in the 4x200m relay at the world championships last year, a disappointing performance in the individual heats could cost her a place in the side at the Manchester Aquatic Centre.
Only four from around eight possible competitors will make the team and with Belton putting in a below par showing on Tuesday, she could miss out.
And the heartache for the 22-year-old is made more acute due to the lack of competition in the final.
A lack of entrants means the heats have been abolished and only four teams will take to the water in tonight's final.
Australia appear to be the only genuine competitors with Scotland and Wales very beatable opponents.
England not picking up a medal would be highly unlikely and Belton will be desperate for selection after the self-confessed below par performance earlier in the week.
She left the pool close to tears on Tuesday expressing her hope to make up for the disappointment in the relay.
But it is not all gloom for home-grown swimmers, as Sheffield's Zoe Baker won gold in the 50m breaststroke last night.
She had earlier shattered the world record during the heats at Manchester's Aquatics Centre.
After a surprisingly successful Games, England now stand second in the medals table.
