The St. Louis Cardinals aren't making trade calls in search of shortstop help, according to other clubs.

The team is apparently waiting on a second opinion on Jhonny Peralta's thumb.

"If they go outside, I think Erick Aybar has to be at the top of their list. Of the guys out there, he's far and away the best player," one executive said.

Aybar is currently slated to be the starting shortstop for the Atlanta Braves.
