Larwood had played his first Championship season in 1924 and broken into the England side in June 1926 against Australia at Lord's. The 1927 and 1928 county seasons were the period in which he became the leading English fast bowler. In 1927 he took 100 wickets at 17.31 in his first 100-wicket season; in 1928 he took 138 at 17.55 and was the leading wicket-taker in the country. Wisden named him one of its Five Cricketers of the Year for 1927.
His pace, action and stamina were the most-discussed in English cricket. He bowled with a 23-pace approach, a perfect side-on action and a delivery faster than anyone in England since Tom Richardson in the 1890s. He was 5 ft 7 in tall — small for a fast bowler — but the rhythm and the late swerve made him close to unplayable on receptive surfaces. The 1928 county season produced the figures that secured his Ashes selection: 138 wickets, including 9 for 41 against Lancashire at Old Trafford.
The 1928-29 Ashes was the first Ashes win in Australia for 17 years. Larwood took 18 wickets in five Tests at 40.22 — modest figures by his later standards, but enough on flat Australian wickets to confirm his role as England's pace spearhead. The plans for 1932-33, formed at Lord's by Pelham Warner and Douglas Jardine, would centre on Larwood from the outset.
