Cubs manager Mike Quade plans on rotating the three during Cactus League games and would like to see someone assert himself and take the job.
Fukudome, who has a career .368 on-base percentage in his three seasons with the Cubs, may be the best fit there.
"You can't lose sight of the fact that if 'Fuke's' in the lineup and it's his day and he's playing well, he's the guy who fits best to me," Quade said.
Quade did use Baker at the top of the order against some left-handed pitchers last season. Baker boasts a .350 average against lefties.
As for DeWitt, Quade said he's still getting to know the second baseman, acquired from the Dodgers in the Ted Lilly trade.
"His development is crucial to how important he becomes in the middle of this lineup," Quade said. "He's got plenty of work to do."
