Amateur career

Robertson played for Melrose.^[1]

Richard Bath writes of him that:

Keith Robertson never possessed the acceleration which usually marks out the great wings. Yet what he lacked in out-and-out pace he more than made up for in guile and sheer footballing ability. An accomplished Sevens player, the willowy Melrose wing – he was a shade under 11 stone – was also a prolific try scorer at every level except international. During his Scotland career which spanned eleven years, Robertson only managed to score eight tries."^[2]
