I know most of the sources stated that Rondon stood 6'3", but when I looked at the picture at the pre-fight press conference with Bob Foster, you noticed that Rondon didn't stood the same height as Bob Foster, who stood 6'3 1/2". Even at the fight itself, Rondon was shorter than Foster by 2 inches, so Vicente Rondon actually stood 6'1 1/2". Watch their fight and please change Rondon's height from 6'3 to 6'1 1/2".
