Despite another season of limited opportunities in 1951–52—he played in only four matches—Davidson continued to improve. He struggled at the outset, taking only four wickets at 41.25 in his four innings, before breaking through against a full-strength Victorian team. He broke through for his first half-century, scoring 76 before being bowled by Bill Johnston— at the time ranked the No. 1 bowler in the world. He then took 4/93 in the second innings, removing Test captain Lindsay Hassett and Australian representatives Ian Johnson and Doug Ring. He then took five wickets in a match against Queensland before bowling his state to victory over Western Australia in his final match for the summer. He took 6/13 to cut down Western Australia for 50 and took 3/36 in the second innings to seal a 250-run win. Davidson ended the season with 22 wickets at 18.00 and 137 runs at 27.40.
