I hate locking up the utility spot but Berkman is certainly the best of the bunch if 1B was open.
How long can you wait to decide? If you continue to hear good news from Upton regarding his injury then I might go with him. Phillips is another option. McCann is not worthy to be in the class of the other four and Phillips is better than Youkilis at a weaker position so I would rule Youkilis out also.
Tough call but I would go with this:
1)Upton
2)Berkman
3)Phillips
