I'm not as strong as Martinez, and I can easily make a ball do that. I love Mings and Martinez, so I'm not biased at all and the replays make it look like Martinez 100%. I'm not sure why you'd think this is a conspiracy to not give Mings his credit.
In fact, the only bit of evidence otherwise is a hilariously unclear photo that doesn't show Martinez's hand. That photo above doesn't help at all.
