0 - Number of fast bowlers to take 400 Test wickets at a younger age than Stuart Broad, who was 31 years, 271 days on day one in Auckland. The previous youngest was Dale Steyn at 32 years, 33 days, when he got to the milestone against Bangladesh in 2015. Among all bowlers, only Muttiah Muralitharan and Harbhajan Singh have reached 400 at a younger age than Broad. Muralitharan, at 29 years, 270 days, is the youngest to 400 Test wickets overall. Broad is the second England bowler, after James Anderson, and the 15th overall to take 400 wickets.

1 - Fast bowler to have reached the 400-wicket mark in lesser time from date of debut than Broad, who has taken 10 years and 103 days. Glenn McGrath raced to the feat in just 8 years and 341 days, which is the fastest among all bowlers. Spin legends Muralitharan and Shane Warne also took less than 10 years to get there. However, Broad has taken 115 Tests to complete 400 wickets, which is the joint-most among the 15 bowlers to the mark, alongside Kapil Dev's 115.

196 - Wickets picked up by Broad in a span of four years between 2013 and 2016, the most by any bowler in that period. He averaged 25.56 and took a wicket every 52 balls in that period. He averaged less than 30 in each of those four years, and was the top wicket-taker among pace bowlers in calendar years 2013 and 2015. Till end of 2012, he had picked up 172 wickets at 31.93 in 52 Tests.

Stuart Broad's career
Period Mat Wkts Ave SR 5WI 10WM
 2007 to 2012  52  172  31.93  62.9  6  1
 2013 to 2016  50  196  25.56  51.9  9  1
 2017 onwards  13  32  38.34  81.9  0  0

However, he did not have a great 2017 as he managed only 30 wickets in 11 Tests at an average of 36.06 and strike rate of 78.4. The strike rate was his worst in any calendar year. In 2018, so far, he has played two Tests and taken two wickets.

8/15 - Broad's career-best figures, which came against Australia at Trent Bridge in the Ashes 2015. They are the best figures for any fast bowler in the last 20 years. In the last 10 years of Test cricket, Mitchell Johnson is the only other pace bowler to have taken eight wickets in an innings.

66.67 - The percentage of Broad's five-wicket hauls that became six-wicket hauls. He has 15 five-fors, out of which 10 times he took six or more wickets in the innings. Among the 74 bowlers who have taken 10 or more five-fors in Tests, no one has a better five-fors to six-fors conversion percentage than Broad. In the last 10 years, Broad has 10 six-fors, while the next most among fast bowlers is six by Steyn.

11 - The number of times Broad has dismissed Michael Clarke - the most has he got any batsman. Next on the list are AB de Villiers (10), Ross Taylor (9, ahead of the Auckland Test), Hashim Amla (8), Shane Watson (8) and Chris Rogers (8). Coincidentally, each of these six batsmen have also got out to Broad the most times in their career (Watson had also got out eight times to James Anderson).

19.17 - Broad's bowling average in the fourth match of Test series, his best among all matches of a series. He doesn't average less than 27 in any of the other matches. He has taken 63 wickets in 14 such Tests with five five-wicket hauls (four of them six-fors). Out of his nine Man-of-the-Match awards, four of them have been in the fourth match of series. His best bowling figures (8 for 15) and only century with bat (169 runs) also came in such matches.

202 - Wickets for Broad under Alastair Cook's captaincy - the most by any bowler under an England captain.

Anderson took 191 wickets in 49 Tests under Cook.
