Keeton made his debut for Nottinghamshire's second eleven in 1925 and the following year made his first-team debut, playing in two
County Championship matches as a lower middle-order batsman. The Nottinghamshire side of the late 1920s was a settled and successful unit under the captaincy of
Arthur Carr, with apparently ageless batsmen such as
George Gunn,
Wilfred Payton and the slightly younger
William Whysall,
Willis Walker and Carr himself dominating the batting line-up. Keeton and other young batsmen such as
Charles Harris and
George Gunn junior were given few first-team opportunities, and Keeton played in just five games in 1928 and two in the Championship-winning season of 1929 – one of those two was against
Oxford University – and none at all in both 1927 and 1930. (In practice, the policy was modified and Gunn played fairly regularly in 1931 and 1932, and Payton was also recalled for a few matches in 1931.) Promoted to open the innings (often alongside Gunn), Keeton responded with an unbeaten century in the game against
Essex in June 1931 and thereafter was a regular in that position for the rest of the season. By the end of his first full season of first-class cricket he had amassed 1233 runs at an average of 30.07. That first full season was just the prelude to highly prolific run-getting by Keeton in the next three years, in which he passed 2,000 first-class runs in each season. Later in the same year he improved on that highest score with an innings of 242 against
Glamorgan, made in 330 minutes with three sixes and 27 fours. By the end of the season, Gunn having been injured and then retiring, Keeton had been joined by Harris as his regular opening partner, and the partnership continued up to the
Second World War and, on occasion, after it. That Keeton may have been in the minds of the
England Test team selectors was shown by the fact that he was picked for a
North v South match, a Test trial
England v The Rest game that was almost entirely washed out by rain, and the
Folkestone edition of the
Gentlemen v Players series in 1932, though he was not conspicuously successful in any of these games. By the end of the 1933 season, according to ''
Wisden Cricketers' Almanack, Keeton had "firmly established himself as the best batsman in the team". The Wisden'' report went on: "To those who followed the team he recalled memories of the County's greatest batsmen. Though scarcely comparable in method to the giants of the past because of the changed type of most bowlers met in these days, Keeton developed the highest art in defence and run-getting. Possessed of all the strokes, he was especially strong in such attractive features in a batsman's make-up as cutting and off-driving... Keeton, if slow to mature, found himself at the age of 28 in his third full season with the County, mentioned with
William Gunn, George Gunn and
Arthur Shrewsbury." He scored more than 1000 runs in August 1933 alone, with six centuries in the month, including four in five innings. But again his representative cricket was confined to a few end-of-season matches of doubtful seriousness. ==Test cricketer==
