Pitching seems to be the No. 1 priority for the Colorado Rockies this off-season -- with good reason, considering the league-worst numbers that the rotation put up in 2012 -- and they could look at Detroit Tigers righty Rick Porcello. Denver Post beat writer Troy Renck was asked about Porcello on Twitter and confirmed that the Rockies do indeed 'have interest' on Sunday. He also pointed out that Porcello is in line for some good arbitration cash:

Porcello also in line to make some $ in arbitration, $4 to $5 mill. Is he be better than other young guys have? I like him. But worth asking

The 23-year old had middling statistics in 2012, going 10-12 with a 4.59 ERA and only 107 strikeouts. If brought in to Colorado, he would likely provide another body for the tail end of the rotation, but the Rockies struggled so mightily last season with their rotation all over that they're looking for anyone who can contribute meaningful innings at this point.
