Kallis is one of only four players in Test history (after Sir Donald Bradman and before Mohammad Yousuf and Gautam Gambhir) to make a century in five consecutive matches, which he achieved in the 2003/04 season. For his performances in 2004, 2005, and 2008, he was named in the World Test XI by ICC. He was also named in the World ODI XI by the ICC for the year 2004 and 12th man for XI in 2005. He was also selected for the ODI XI in 2007 as well. In 2005, he set the record for the fastest half-century in Test cricket history, scoring 50 against Zimbabwe off only 24 balls. In 2007, Kallis scored five centuries in four Tests, making him just the fourth man after Bradman, Ken Barrington and Matthew Hayden to score four centuries in four Tests on two different occasions. Kallis has a remarkable batting average in the mid-50s, and was consistently rated as one of the best batsmen in the world. Although a very capable bowler with 292 Test wickets, he impressed mostly with the bat between 2005 and 2007. As a result, he evolved into more of a batting all-rounder, a role in which he continued because of the emergence of Dale Steyn, Morné Morkel, and Vernon Philander. Kallis is the only man to score over 10,000 runs and to take over 200 wickets in Test cricket. Sir Garfield Sobers managed over 8,000 runs and 200 wickets by comparison, at very similar averages.
