Seriously, good luck. I wanted to duplicate stitch the Red Sox logo on the back of a wool soaker and couldn't get the knitPro to cooperate. So I Googled my fingers to the bone and ultimately found one online in someone's blog that she had created. She didn't share it with me, but did offer me advice on how to create it.
Knitty has this article
which works, but the result was too blocky for my taste. So the soaker was gifted with a bare behind.
Cross-stitch charts for major league logos are available online for purchase. I didn't go that route yet, but will in the future.
