Here’s a good article on Eduardo Rodriguez and how his teammates are working with him to get rid of his tells:

“We made it a point to let him know it,” Buchholz said. “We watched video and showed him what was going on. He had no idea that he was doing anything wrong or anything different on any one pitch. These last four days that’s all he’s been talking about is working on it. He’s been the hotel room in front of a mirror he’s been working on it. He did a good job on it today. Especially a team like that, if you’re letting him know or giving them a hint what’s coming or what’s not coming, it’s not going to be a fun day at the park. He did a really good job with the adjustment.”

Of course, if Rodriguez really wanted to be evil, he would show the tell and make the other pitch. 🙂
