 In Worcestershire's final game of the 1920 County Championship, Greig enjoyed his best performance with the ball, claiming 7-86 in Lancashire's first innings, five of the dismissed batsmen being out bowled.His feat was in vain, however, as Lancashire triumphed by nine wickets to leave the county languishing in 16th place in the final Championship table.Grieg played five matches in 1921, taking nine wickets at 40 apiece, but after that his first-class career was almost at an end, and he was to play only two more games, these coming almost four years later.
