Don and Derek Pringle (East Africa/England)
A landscape consultant, who moved to Kenya in the late 1950s, Don Pringle's World Cup career was a cameo in hindsight. He was 43 when East Africa was invited to play in the inaugural World Cup in 1975. He played just two matches, went wicketless in both and sadly died in a car crash in Nairobi four months later after picking up 6-16 in a club match. However, he earned a posthumous place in the history books in October 1987, when his son, Derek, took the field for England against West Indies at Gujranwala. Pringle Jr's first outing was even less successful than that of his father — he was spanked for 83 runs in 10 wicketless overs, which was (for four days) the most expensive analysis in World Cup history. But he bounced back in style, and in the next tournament (1991-92) he took 3-22 in the final against Pakistan at Melbourne... only for Wasim Akram to upstage him in the second innings and snatch the trophy from England's grasp.
Lance and Chris Cairns (New Zealand)
A strongly-built swing bowler and a hard-hitting batsman, Lance Cairns had a pretty ordinary World Cup career. Lance played 11 matches in the first three editions of the World Cup, but only managed 43 runs with the bat, with a highest of 14. He had some success with the ball though, picking up 14 wickets at an average of 31.14. Cairns Jr made his ODI debut within six years of his father's retirement, which meant that between 1975 and 2003, there was only one World Cup (1987 edition) where neither of two Cairns were present. In 28 World Cup games, Chris aggregated 565 runs (avg 33.24) and took 18 wickets (avg 41.94). His best performance came against arch-rivals Australia in 1999 at Cardiff. He had a rather forgettable outing as a bowler conceding 44 runs in seven overs, but played a significant role with the bat in handing Australia a five-wicket defeat. Cairns came out to bat with New Zealand reeling at 49-4 and added 148 runs with Roger Twose. Cairns contributed 60 off 77 balls with 5 fours and three sixes.
Chris and Stuart Broad (England)
Both Broads had pretty ordinary World Cup careers. Chris played his only World Cup in 1987, and in three matches, scored just 67 runs. Stuart became the second youngest Englishman (after James Anderson) to appear in a World Cup game (in 2007). He played only one game, against hosts West Indies, without doing anything of note. In the 2011 edition, Stuart played three games. He went for plenty of runs against Netherlands and Ireland, but made amends by picking 4 for 15 against SA in a match England won by 6 runs.
