  In a competitive sport, every little thing matters. Yet, many sports leave
some large levers out of the reach of the teams, and in the hands of fate. In
cricket, world's second most popular sport by some measures, one such
lever---the toss---has been subject to much recent attention. Using a large
novel dataset of 44,224 cricket matches, we estimate the impact of winning the
toss on the probability of winning. The data suggest that winning the toss
increases the chance of winning by a small ($\sim$ 2.8\%) but significant
margin. The advantage varies heftily and systematically, by how closely matched
the competing teams are, and by playing conditions---tautologically, winning
the toss in conditions where the toss grants a greater advantage, for e.g., in
day and night matches, has a larger impact on the probability of winning.
