Canadian sensation Summer McIntosh fell just short in her quest to match Michael Phelps's feat of winning five individual gold medals at a single world championships but that has given her the motivation to improve even more.

Summer McIntosh is off to a perfect start at the swimming world championships with two gold medals in two days.

Make that three world championship gold medals for Canadian swimmer Summer McIntosh. The 18-year-old from Toronto won the women’s 200-metre butterfly Thursday in a meet-record two minutes 1.99 seconds, which was just shy of the world record of 2:01.81.
