Right Elbow Buckles Inward on Bench Press

Hey guys I am new to this website, but I googled my question and a similar question came up in google but it wasn’t exactly the same. If this question has already been answered ill apologize, and no I have not gone through this whole website looking for my answer. Don’t have time to do that. But anyways when I bench my right elbow will come closer to my body for no reason.

The left elbow goes up and down normally no problem. I played college baseball for two years and I was a pitcher who threw right handed. never had any shoulder problems and It has been two years since I last played so I know that it cant be inflammation from that. I do a ton of push ups also as I am training for the military when I graduate which will be this summer. I feel their is a direct correlation to push ups and bench so I would like to get my bench press up.

So if any advice would like to be given thank you very much.
