If last year is any indication, you might be waiting a while. Assuming Ortiz is either at U or on your bench, I'd try to acquire someone like Francoeur, Krispie Young, Ludwick, etc. In other words, a player that's better than the available FAs and has the chance to produce for you. Ortiz was dropped in my league for the shortstop, Alex Gonzalez...telling.
