This photograph by Scott Barbour was the inaugural winner of the Wisden & MCC Cricket Photograph of the Year Award. The images were all about capturing the the joy, spirit and essence of cricket. To me, this photograph has great dynamism and the photographer caught the delta or V formation of the team members running towards the bowler at just the perfect moment. The strength is not just in that, but also in the powerful dynamism of the inverted triangle.

Curiously, or perhaps not, the second-placed photograph of 4 players forming a triangle whilst making an "appeal" is also incredibly powerful. This underlines how the triangle as a design element is visually so powerful.
