9. Phil Simmons' Economy Rate of 0.3 in a One Day International
If you bowl out ten overs in a one-dayer, the yardstick for a good performance to finish with an economy rate of less than four runs per over (that's under 40 runs conceded).
Against Pakistan in 1992, the West Indies' Phil Simmons gave away just three runs for an economy rate of 0.3 runs per over.
ODIs have become much more attack-minded since, so Simmons—who was primarily a batsman—can be confident that his run rate won't be bettered.
