A nephew of ex-Victoria player Ambrose Tarrant, Tarrant first played for Victoria in 1898/1899, and met with little success either as a batsman or a bowler then or in 1900/1901. However, he moved to England in 1903 to join the Lord'sground staff and played a number of matches for the MCC while qualifying for Middlesex. In these, he showed himself developing into a left-arm spinner of above average pace but with nothing beyond steadiness when pitches did not help him. In 1904, he showed development as a solid right-handed batsman, and in 1905, when fully qualified, he was a valuable aid to Middlesex. his superb batting on a difficult pitch to draw the game with Essex at Leyton showed he was a player of exceptional resolution during the most difficult crisis. In 1906, while his bowling was impotent on the rock-hard wickets prevailing in the Home Counties for most of the season, Tarrant was unplayable on rain-affected pitches at Old Trafford and in Yorkshire, and he scored 1000 runs for the first time. 1907 saw Tarrant take a leap into cricket's elite, with his batting, at least for three months, marking him as a player of remarkable patience even if he failed to use all the strokes he was capable of playing. Though he lacked sting when pitches were hard, on rain-affected pitches Tarrant could turn the ball extremely quickly from a perfect length. This was seen at its clearest when he took nine for 59 against Nottinghamshire at Lord's – some of the batsmen said they "had never seen a finer piece of bowling". For the whole season Tarrant took 183 wickets for 15.70 each and scored 1552 runs with an average of 32. That winter, Tarrant returned to Australia and in six matches scored 762 runs for an average of 76, including 159 against the touring MCC team and 206 against New South Wales at the SCG. Between 1908 and 1914, he was always one of the best all-rounders in the game – a safe catcher, a skilful opening batsman, and a deadly bowler when the wicket was helpful and steady when it did not. His batting also grew beyond the purely defensive as he developed his on-side strokes – so much that against Surrey at Lord's in 1911 he scored 89 in seventy minutes when Middlesex wanted quick runs for a declaration. That year he achieved the rare feat of scoring 2000 runs and taking 100 wickets, and carried his bat for 207 against Yorkshire. His performance of taking 16 for 176 followed by 101 not out against Lancashire in 1914 remains one of the greatest all-round feats in county cricket. That same year, he scored a brilliant 250 not out at Leyton after Johnny Douglas had put Middlesex in to bat on a rain-affected pitch. As he scored 200 against Worcestershire in the following match, he accomplished the remarkable feat of scoring two successive double-hundreds. With J.W. Hearne he forged a partnership that, almost single-handed, allowed Middlesex to come second to Surrey. During the war, Tarrant played in India, and his bowling was unplayable on the matting wickets against weak batting. In 1918/1919 he achieved . Tarrant continued to organise touring teams to India after the war, and only played rarely outside India. However, he managed to make 78 in one match as late as 1936/1937, when he was fifty-seven, and he umpired England's first two Tests on Indian soil, as well as several other MCC matches on that tour. Tarrant and his son Louis stood together in the match between MCC and Southern Punjab, which provides one of the few instances when a father and son umpired in a match, and later also appeared together in a first-class match during the 1935–36 season. On 26 August 1909, playing for Middlesex against Gloucestershire, Tarrant did the double by taking a Hat-trick and carrying his bat in the same match; he is the only cricketer to do so.
