Weaver was moved to the bullpen Friday, Jenifer Langosch of MLB.com reports.

EDGE Analysis

Weaver's big league career started off fairly auspiciously, but after two rough outings, the Cardinals decided that they'd like to have him pitch in relief the rest of the season. Jaime Garcia will rejoin the rotation in his place, although the top prospect will likely compete for a spot in the rotation next season given his high promise and nasty pitch repertoire.
