Thanks Kim!

No, I didn't save it as a preset. I usually adjust the white balance based on the particular shot, and then if there are several pictures shot under those same conditions, will do a sync in the LR Develop module and apply that to the remaining pictures, then check each one to make sure what I've applied works on them all, and make any adjustments if I need to. For basic photo processing I tend not to use a lot of presets.
For this particular one, I ended up using the person's shirt up in the top right corner as my neutral. I moved the eye dropper around until I got readings of approximately R=80.3%, G=79.2%, and B=79.4% In LR, the target neutral (at least according to Mikkel Aaland in his book "Lightroom2 Adventure" where I learned this) can be any spot where the RGB values are all within 1% of each other. I just as easily get the same result by picking targeting the black shorts to the left side of the picture. ACR handles things a bit differently and it doesn't seem to need to be a neutral gray (where the values are in the 60% target range). The rendering below used a spot off the black legging of our wrestler with the orange tank top. I poked around until I found a spot that measured R=12.9%, G=12.4%, and B=12.4%.

The % measurements are seen at the bottom of the box that follows the eye dropper tool around in LR.
I then did a couple HSL adjustments. In Saturation I clicked the circle in the top left corner that allows you to adjust by selecting a point in the photo and dragging up or down. For Saturation, I used the cheek of the orange tank top wrestler and adjusted to eliminate some orange cast. The final number I ended up with here was Orange -20 and Red -2. Then I adjusted Luminance using a point on the orange tank top to Red +5 and Orange +12. These values are very similar for both renderings I did here.
I tried the same thing using ACR in PSE5, but it doesn't show the RGB color values as a %, but is using the 0-255 numbering scale, so this makes it a bit tougher but not impossible to do. Sticking to the same guideline I use for LR, if you can find RGB points with 2 units of each other for all points, it looks like it will work. ACR in CS3 works the same way, except when doing HSL adjustments you can't make the adjustments directly from the picture as in LR, but have to adjust the sliders individually. I was able to get the same results. With either version, PSE or CS, you have the option of applying the previous settings used to the next picture, or in CS you can save your settings as a preset if you desire, as you can in LR.
HTH...
