I got some video of Jon Niese and Taylor Jungmann batting today. I noticed that Niese already has a stance, but I'll still post the info in case there is a better stance.

Additionally, Niese wears all white Under Armour batting gloves, with a bat that is not in game. Jungmann wears grey and blue (possibly white and blue at home) Franklin batting gloves with a white Sam Bat with a black barrel.
