England's opening woes: Alastair Cook's opening partners since 2012

5. Jonathan Trott

Jonathan Trott averaged 19.38 as an opener in 8 innings for England

Jonathan Trott was a reliable middle order batsman and scored heaps of runs batting at number 3 for England. In 73 innings at number 3 for England in Tests, Trott scored 3109 runs at an average of 47.72 with 7 centuries and 15 half-centuries.

The England team management decided to promote Trott as an opener in the 2015 series against the West Indies. However, Trott could manage only 72 runs in 6 innings against the West Indies and averaged just 12 with 3 ducks.

Trott immediately announced his retirement after struggling against the West Indies. His only notable contribution was an innings of 59 in the 2nd Test which saw him add 125 runs for the first wicket with Cook at Grenada.

In 8 innings as an opener, Trott scored 155 runs at a dismal average of 19.38 which is way lower than his career average of 44.08.
