"In my book, long man is being better than no man," Baker said. "You want to be on a team -- especially a team that has a chance to win. You want to be on the team regardless of what your so-called role is."
Todd Wellemeyer, who is out of options, could be a leading candidate even though he is struggling in camp in the hitter-friendly environment of Arizona.
Baker said that Michael Wuertz and Roberto Novoa, both setup man in 2005, are also candidates. With left-hander Scott Eyre and right-hander Bobby Howry on the roster, players like Wuertz, Novoa and Will Ohman will have their roles shifted around.
If the Cubs go with a four-man rotation in the first two weeks of the season, it's possible starter Jerome Williams could open the season as a long man in the 'pen.
