6:16pm: The Diamondbacks are unlikely to acquire Porcello, according to Nick Piecoro of the Arizona Republic (on Twitter).

10:53am: The Tigers would likely ask for a shortstop, a late-inning reliever or a right-handed hitting outfielder in a trade for Porcello, Morosi adds. Detroit doesn't appear to be a finalist for Scott Hairston, who could decide between the Yankees and Mets.

8:14am: The Diamondbacks have talked to the Tigers about trading for starter Rick Porcello, Jon Paul Morosi of FOX Sports reports (on Twitter). Morosi confirms that the Mariners have also had talks with Detroit about Porcello. The Angels, Pirates, Padres, Orioles and Cubs have also been linked to Porcello this offseason.

The 24-year-old posted a 4.59 ERA with 5.5 K/9, 2.2 BB/9 and a 53.2% ground ball rate in 176 1/3 innings this past season. He earned $3.1MM in 2012 and has a projected salary of $4.7MM for 2013. He’s under team control through 2015.

Arizona has many internal starting pitching options, including Ian Kennedy, Brandon McCarthy, Trevor Cahill, Wade Miley, Tyler Skaggs, Josh Collmenter and Patrick Corbin. Plus, Daniel Hudson could return from Tommy John surgery midseason. However, GM Kevin Towers has shown this offseason that he’s willing to add to apparent areas of depth. Last month Towers signed Cody Ross even though the Diamondbacks' outfield seemed full to most outside observers.
