I think Hassell plays everyday in Rochester and either comes up to displace Young, or they move Wood to DH (replacing Bell).
I don't think they'll DH James Wood this year unless worried about durability.
For James Wood to DH in full health is not great. Part of the high upside is he had the impact bat plus a glove that maybe could hold up in CF. It was unlikely he'd make it in center, but at least he'd be a plus in the corner. I look at last season as new to the bigs and mostly new to LF. If in year 2 in the leagues he profiles as a DH, ouch. The bat has potential to be special, but if he needs to live at DH, the long term ceiling drops.
Good thing is I don't think it will be a problem. Unless Wood is a true disaster, I am fine riding out his growing pains in LF for at least a couple years.
I'm not worried about a massive OF crunch. An OF crunch means everyone is healthy, neither Crews nor Wood has fallen off, Jacob Young has improved his hitting a bit,
and Hassell has hit his way out of Rochester. If that happens, it's a good problem. It's not that hard to find ABs. Hassell and Young can rotate or both play if Martinez wants to find some off days for Woods or Crews, either bench or DH.
