Cardinals general manager John Mozeliak told 101.1 ESPN's Brian Stull that Jake Westbrook's elbow injury isn't a big deal. Westbrook has had Tommy John surgery before, but Stull said Mozeliak was "emphatic" that the righty's current ailment isn't a Tommy John situation. The right-hander has been given an injection in his elbow in hopes of speeding along the healing process. John Gast is taking Westbrook's spot in the rotation starting Tuesday.
