Ok, I found the problem, but I have no idea what caused it. I got home and examined the lens again very closely, I did find one small dust particle on the inside of the rear element near the edge. Took several different shots trying to see if it was the problem and it was not, wasn't even noticeable.
So, I went back into Lightroom and I was looking at the image which is a raw file (I shoot raw to one card and jpeg to the other as a backup). Of course when they go into Lightroom I tweak them and make adjustments as needed, I don't have a specific preset I use for baseball. I generally start with one image and adjust it too my liking and then sync those settings to every other picture and use that as a starting point. Just for the heck of it, I reset this image. The blotch went away. I returned to the previous settings and went through every adjustment I had made one by one resetting them to the default setting and the blotch never went away, only when I did a complete reset of the image. I Reapplied settings after the reset and the splotch never came back. I have no clue why this happened, but it was Lightroom, not the camera, the lens, the card, etc. I reset a couple of the other images and no splotch. And as noted in my last e-mail, all of these images did not have a splotch, only some of them, and they were all synced the same. I don't know why, but at least I figured it out and I am relieved it's not something major.
