If the Detroit Tigers intend to trade starter Rick Porcello before spring training, they still haven't found a partner.

That apparently doesn't mean the phone lines have been dead.

According to FoxSports.com's Jon Morosi, the Tigers have discussed trading the right-hander with the Seattle Mariners and Arizona Diamondbacks.

Morosi did not indicate any other players being discussed.

Porcello has become expendable after the Tigers re-signed Anibal Sanchez to a five-year, $80 million deal in the offseason, and also appear to be willing to enter 2013 with left-hander Drew Smyly as their fifth starter.

The Mariners and Diamondbacks would be just two of the latest teams that have inquired about Porcello.

The Pittsburgh Pirates, San Diego Padres, Los Angeles Angels and the Chicago Cubs also are reported to have interest in the 24-year-old Porcello.

A report surfaced last week the Cubs were interested in acquiring Porcello in a three-team trade involving the Baltimore Orioles. Detroit presumably would have interest in shortstop J.J. Hardy as part of the deal.
