the easiest way to enter those is by just a copy from the pdws and paste special into the proper col of the wa nps.
i explain where these drop down come from and how to update if you want to, as i dont have time or forget to update that list and new pitchers get added every day, but the stats for those pitchers are correct once you post special the correct name in that col
just scroll down in the wa nps tab under the p col, and starting in row 50 in col E and P you will see the starting pitchers (col e) and visiting pitchers in (col p)
that is where the drop down pick up the pitchers from, the actual data for those names is in the master area and even if the pitcher name is not in that col the data for him once you post his name propery in the wa nps comes up with the correct stats. i'll update that list this morning, but here how you do it, will only take you a couple of min
find the PitcherOverUnder Tab (it's in the Red Tabs area, these are pivot tables that only support the popsummary and wa nps.
find col Q, and starting in row 5 click on armas, jr and drag you mouse all the way down to the last pitcher zito, than do an edit copy, and paste special that one col into col e and col p, they are the same group of names and i aways take the longer one and put it into both, but some could have been only started as the visiting pitcher etc
let me know if you understand the process and can make the change. i've already updated this area in my master, so they will be there tomorrow
