STEVE Smith has scored almost one-third of Australia’s centuries across Tests, one-day internationals and Twenty20 internationals over the past three years.

And he has notched more tons and scored at a higher average than any other batsman in international cricket during that span with a minimum of 21 matches played.

At a time when Australia’s fortunes have fluctuated wildly, Smith’s returns of 3515 runs at 68.92 in the Test arena, 2428 runs at 51.65 in ODIs and 266 runs at 29.55 at T20I level have been remarkable in their consistency over the last three years.

Check out these remarkable stats:

MOST CENTURIES ACROSS ALL THREE FORMATS

Smith has scored more centuries than any other international batsman over the last three years — across all three formats and in Test matches, specifically.

Smith’s ground record innings of 164 from 157 deliveries at the SCG on Sunday was his 21st across Tests, ODIs and T20Is during that period, ahead of Virat Kohli (19), David Warner (19) and Hashim Amla (17).

Smith’s 14 Test tons over the last three years are also the most in international cricket. The only other batsmen to crack the double-figure mark are Warner (12), Younis Khan (11) and Kohli (10) during that span.

HIGHEST AVERAGE ACROSS ALL THREE FORMATS

No batsman in international cricket can match Smith’s average across all three formats over the last three years.

Here’s how the top five batsmen rank by average over that time frame (minimum 21 matches):

- Smith 6209 runs @ 58.02

— Kohli 6241 runs @ 57.25

— Williamson 6393 runs @ 55.59

— Sangakkara 4384 runs @ 54.12

— de Villiers 4538 runs @ 52.16

Tuesday’s ODI in Canberra will be Smith’s 100th Test, ODI and T20I match across that three-year span.

SMITH, WARNER, DAYLIGHT

Smith (21) and Warner (19) have combined for more than half of Australia’s 76 centuries across all three formats over the last three years.

That percentage (52%) is, by some margin, the highest proportion of any of cricket’s top seven international sides.

Here’s how the other six nations compare:

— Joe Root (17) and Moeen Ali (6) accounted for 37% of England’s 62 centuries,

— Virat Kohli (19) and Ajinkya Rahane (10) accounted for 44% of India’s 66 centuries,

— Younis Khan (12) and Azhar Ali (10) accounted for 35% of Pakistan’s 63 centuries,

— Hashim Amla (17) and AB de Villiers (13) accounted for 41% of South Africa’s 74 centuries,

— Ross Taylor (15) and Kane Williamson (15) accounted for 49% of New Zealand’s 61 centuries,

— Kumar Sangakkara (14) and Angelo Mathews (7) accounted for 36% of Sri Lanka’s 59 centuries.

SMITH’S INDIVIDUAL TON PERCENTAGE

Only Kohli can claim to have scored a higher percentage of his team’s total centuries across all three formats over the past three seasons.

Kohli’s 19 tons represent 29% of India’s total tons, while Smith’s 21 and Root’s 17 account for 28% and 27% of Australia and England’s respective totals.
