OOTP 27 has added the ability for the game to add logos to the batting helmet. The problem is it pulls the logo from the "small logo" box in the uniform screen and some teams don't use this logo on their cap. For more detail here is a link to the relevant post and thread started by cheo25.

I think the only teams that need a logo are the Red Sox, Reds, and Cubs.
I tried dabbling in this for a bit this morning and made the "C" (red C, white border) from the Cubs cap into a150*150 small logo. I think it's ok, but someone who knows what they are doing could probably do better. You'll see there's still a little blue border around the white trim. I don't notice it on the dark standing screen (haven't tried the others). And beings the Cubs helmet is blue it should disappear there too, I think.
I'm including a screenshot of the logo (right click-save image if you want to try it), uniform page (don't know why I get the black screen? but the logs you can see in the small logo box), and standings with my logo. I'm nowhere close to playing out games yet (just started off season from my import) so haven't seen it in a game. I think it's ok on the standings page.
I may try the others later unless someone else comes along and does them. Also if someone wants to clean mine up or makes a better one I won't be offended.
