That seems about right to me. Murton should get every at-bat against left-handed starters. That should be somewhere around 200 PA right there. If he gets even 1/3 of the starts aginst right-handed starters, then that would put him at 350, and pinch-hitting and double switches could probably push him up to 400. Jones ends up getting the most at-bats because he is the only one reliable enough to play RF right now (I hope that Murton gets out there and gets acclimated quickly to RF so Murton and Floyd can play against some lefties, I don't want to see Floyd in RF at all), and Floyd takes the rest of the right handed at-bats from Murton and a few of the left-handed bats from Jones. I know many of you hate this practice, but history against certain pitchers might dictate some of the matchups. I don't mind it in a situation like this when the players are likely to be similarly productive anyway (although in different ways)-it's bad when you start Blanco over Barrett because of it, but I think it can be helpful in deciding between similar players for that day. I can also see Lou changing his lineup based on which way the wind is blowing at Wrigley. Forgot to factor in their PH predictions... that's another 93 PA for Murton, which would give him more overall PA than Floyd or Jones (they didn't predict PH for either of them...)
