Fielder took six wickets or more on 13 occasions during the 1906 season and 172 in total for the county. He is one of only four men to take more than 150 wickets in a season for Kent, a feat he repeated in 1907 when he enjoyed another good season, again taking 172 wickets in total for Kent at an average of 16. Fielder was selected to tour Australia again in 1907–08 with England. He played in the first four Tests on the tour taking 25 wickets at 25.08, England's second leading Test wicket taker on the tour. He took 6/82 in a narrow defeat at Sydney in the first Test and scored 18 runs in a crucial last wicket partnership the final innings of the second Test at Melbourne as England won by one wicket. Whilst strictly a tail-end batsman, he scored an undefeated 112, his only first-class century, against Worcestershire at Amblecote batting at number 11 and shared a partnership of 235 for the tenth wicket with Frank Woolley who scored 185. This is still the highest last-wicket partnership in the County Championship. The pair came together when Kent were still 40 behind Worcestershire's first innings of 360 and raised Kent's total to 555. Kent went on to win by an innings. Woolley had retired hurt earlier in the innings after being hit in the mouth by a ball from Ted Arnold. Fielder remained a major part of the Kent team until 1914, taking over 100 wickets in 1909, 1911 and 1913. He was part of the Kent Championship winning sides of 1909, 1910 and 1913. World War I ended Fielder's first-class career although he did play two non-first-class matches for the MCC after the war. Style of play Fielder was described by Wisden in 1907 as being "quite modern in his methods, keeping the ball for the most part well outside the off-stump". He generally bowled out-swing deliveries, swerving the ball away from the batsman and relying on catches by slip fielders. He also used deliveries which made the ball break back into the batsman and is described, again by Wisden in 1907, as bowling at a "fine pace". He bowled consistently and could be relied upon to bowl long spells. He had an unusual run-up. A contemporary account described it: "Fielder ... has three distinct paces when running to the wicket, and at each change he
