JM Anderson took Elgar’s wicket with the 1st ball of a Test (and the series).
Taking a wicket with the first ball of a match is rare enough to merit a separate list:

Anderson is playing in his 150th Test. This by itself is no big deal. But he extends his record of the most Tests without ever captaining his side. Next in line is Warne (144) and Broad (playing his 135th Test) and VVS Laxman (134).
AK Markram is playing his 20th Test. His previous 19 Tests included 11 wins and 8 losses and no draw. He holds the record of the most Tests played without a draw. Next is old-timer GA Lohmann (18 Tests, 15 wins, 3 losses) followed by current player KK Jennings (17/12/5) and Alok Kapali (17/0/17). Jennings may play in the future.
Update: Markram played in his 20th Test at Centurion which SA won. So he extended his record to 20 Tests without a draw (12 wins and 8 losses).
ALSO-6 of the playing 11 for England have a given name starting with J: Anderson, Archer, Root, Denly, Buttler and Bairstow. Would this domination by one letter be a record? Maybe there have been Pakistani teams with more players with names starting with M?
Another oddity: South Africa now have two different Test players named D Pretorius. The earlier Dewald P played 4 Tests in 2002-2003 as a pace bowler:

Today Dwaine Pretorius, a pace bowling all-rounder, made his debut:
