The Cardinals are shopping for an upgrade at shortstop and Peter Gammons of Gammons Daily hears that Jed Lowrie of the Athletics is now on their list. The A's could theoretically move Lowrie to fill a need elsewhere and promote Addison Russell to the majors this season.

Meanwhile, despite the speculation that the Athletics would move Lowrie, Ken Rosenthal of FOX Sports (on Twitter) hears that it won't happen. The plan all along has been for him to be a two-year bridge to Russell and they are now entering year two.

Lowrie, 29, hit .290/.344/.446 in 662 plate appearances last season for the A's. The veteran came to Oakland in a five-player deal with the Astros in February 2013 .
