Though King focused on bowling throughout his career, he was also a very fine batsman. In 1905, he established a North American record batting record by scoring 315 at the Germantown Cricket Club. The following year, he scored 344 not out for Belmont against the Merion Cricket Club, setting a North American batting record which still stands. He scored 39 centuries in his North American career, and he topped 1,000 runs in six seasons. He took over 100 wickets in eight seasons, including a double of 1,000 runs and 100 wickets in four seasons. In his whole career, he scored 19,808 runs at an average of 36.47, and took 2,088 wickets at an average of 10.47. He took all 10 wickets in an innings on three occasions, and took 9 wickets in an innings five times. One of these occasions, in the Gentlemen of Ireland's first innings in 1909, was followed by a hat-trick in the second innings.
