Lind has been a great surprise this year and by the looks of his approach, I think he will continue to be a strong weapon in our lineup. That being said, many thought Lawrie would take a step forward and that hasn't happened yet, so its somewhat of a wash (although Lind is performing better offensively than what most probably expected out of Lawrie).
Adding Reyes will give this lineup 4 well above average bats in Reyes, Bautista, EE and Lind, not counting Rasmus who has been pretty good overall as well. If Melky gets going, this lineup will be that much better.
I think Reyes comes back this weekend, but if not, then probably at the beginning of next week.
