In early May 1925, he claimed his first five-wicket haul when he took 5–40 against Sussex at Fenner"son He also claimed five-wicket bags for Cambridge that season against Free Foresters (taking nine in the match) and Surrey, the three bowling feats coming within a space of six weeks.
He ended 1925 with 41 first-class wickets (his highest season"s aggregate) at 32.21.
