The Angels are unlikely to part ways with shortstop Erick Aybar an industry source told MLB.com late Tuesday night but second baseman Howie Kendrick remains in play.

The Angels and Cardinals engaged in brief talks for Aybar as Jim Bowden of ESPN first reported but it was the Cardinals that approached the Angels first and the talks quickly faded according to a source. The Angels are trying to acquire cost-controlled starting pitching but would prefer not to trade Aybar because a shortstop is much more difficult to replace.

Kendrick however can block deals to 12 different teams in 2013 (whereas Aybar’s contract doesn’t have any no-trade protection).

Earlier on Tuesday the Angels flipped third baseman Alberto Callaspo to the A’s for Minor League infielder Grant Green. The deal saved about $6 million in salary through 2014 which they can allocate towards starting pitching and gave them an option to replace Kendrick if he’s traded.
