I'm more worried about Stairs breaking in half if he tries to stretch like Morse can.
Seriously, though, with Zimmerman not at full strength, it could be a long day at first.
I'm actually not too pissed about Stairs giving Morse a day off. I think Stairs is capable of going 2-5. (If he gets 5 AB's.)
However I don't know that he should be cleanup but oh well.
