Wheeler was brought up to replace Helton at 1st when Pacheco could have had some regular playing time. It would have made more sense to bring up Arenadoto replace Nelson whose performance has been underwhelming to say the least.
Turns out he was suffering from neck and back issues and is having an MRI on his surgically repaired shoulder. Looks like we might not be seeing Lilly any time soon. Just another Dodger pitcher with an ailment.
