Ace Indian swimmer Sajan Prakash’s campaign ended at the Commonwealth Games as he failed to make the semifinals of the men’s 100m butterfly event in Birmingham on Monday. The seasoned Prakash clocked 54.36 seconds to finish seventh in his heat and 19th overall. The best 16 athletes progress to the semifinals. He had failed to make the finals of his other two events — 50m and 200m butterfly as well. On Sunday, he had finished a disappointing ninth in the men’s 200m butterfly, his pet event.
