The Scot will now turn his attention to the Flanders Swimming Cup in Antwerp this weekend.
The 20-year-old was not out of his depth in Texas, claiming the scalps of home favourite BJ Johnson - who is ranked second over 200m in the United States - as well as Olympians Scott Weltz and Conor Dwyer. The Balfron-born swimmer has also set a target of making just as big a splash back home this summer.
"The Commonwealth Games is a massive year for Scotland and for me personally," said Murdoch. "It would be my first Commonwealth Games and in effectively my own back garden. It is going to be something extra special.
"Every time I raced the 100m breaststroke I managed a personal best. I have already set a personal best over the short-course distance and raced long course in under the Commonwealth time so I feel good."
