Coop has decided on three lineup spots for sure:
Matsui will hit first, Berkman will hit 3rd and Lee will hit 4th.
Everything else is up for grabs. The linked article says Coop hasn't decided on the 5th spot down, and hitting second could be anyone from Bourn to Tejada to Pence to Boone. And, like my favorite album of all time, the lineup changes from day to day. Regard the Coop:
"I've been playing around with it all winter and thinking about it. One day, one guy's here, and one day another guy is there. We have options, and we have some time to decide."
