In 1895, Paish became a professional cricket player for Monmouth before joining Clifton's club.
In 1898, Paish started playing for Gloucestershire Cricket Club, where he became a first-class bowler.
At his peak in 1899, he had the best bowling average in first-class cricket at 18.93, beating W. G. Grace into second place.
He was chosen to play for England against Australia in 1899, but declined as he had committed to a county match against the Australian side and did not want them to get used to his bowling.
At the end of World War I, Paish took a role as groundsman coach for Wagon Works, where he remained until his retirement in April 1948.
