Roger Philip Twells Marshall (born 28 February 1952) is a former English cricketer.
Wisden noted after his debut season that Marshall, "with his flowing ginger hair, brought some colour to the scene".
[4] Playing primarily as a bowler, Marshall took 49 wickets in first-class cricket, which came at an average of 39.32, with best figures of 4 for 37 against Glamorgan in 1973.
[6] Marshall also played List A cricket for the county, making his debut in that format against Northamptonshire in the 1973 John Player League.
He featured in this format even less frequently than he did in first-class cricket, making eleven further List A appearances for Sussex, the last of which came against Kent in the 1978 John Player League.
