(Reuters) - James Pattinson says a between-innings change to his bowling action was behind the five-wicket haul that fired Australia to victory in the first test against West Indies on Saturday and cemented his place in the side for the rest of the series.

The 25-year-old Victorian had mustered up mediocre first innings figures of 0-68 in his first test in 18 months after returning from back and hamstring problems to replace the injured Mitchell Starc in the side.
