~~~Pick up Getz, Iwamura, Morales?

[Dimethod]

Im in a 11 team standard scoring keeper league. I've held onto Aviles i think long enough. Are any of the below upgrades? I have Felipe Lopez to fill 2b, so it doesn't have to be a 2b pickup.

Wavier options:
Akinori Iwamura
Chris Getz
Nick Johnson
Todd Helton
Mike Cameron
Kendry Morales

My Roster:
C Russell Martin
1B Billy Butler
2B Felipe López
3B Chris Davis
SS Jimmy Rollins
OF Nelson Cruz
