LONDON, England: Arianna Vanderpool-Wallace didn’t have the “zap” in her comeback swim in the Women’s 100m semifinal on Wednesday night and she ended up two spots shy of making an historic final for the Bahamas Swimming Federation at the 2012 Olympic Games.

After stunning the field and impressing the spectators at the Aquatics Centre with her first place victory in the qualifying round earlier in the day in a national record time of 53.73 seconds, Vanderpool-Wallace could only muster a fifth place finish in a time of 54.12 that left her 10th place overall. The top eight from the two heats advanced to Thursday's final.
