However, Knobler notes the Tigers aren't necessarily committed to moving one or the other via trade.
Last night, Sandy Alderson told reporters while they will not replace R.A. Dickey with a "number one" pitcher, he intends to add another starting pitcher capable of winning "10-12 games."
Porcello had a very promising rookie season in 2009, but hasn't been able to get on a consistent track since. He throws strikes and has historically kept the ball in the yard in his career, but he allows a lot of baserunners and pitches to a lot of contact. That results in a higher than desired pitch count in his starts with hinders his ability to consistently pitch deep into games. In addition, Porcello is arbitration eligible this winter, and so his projected salary could make him immediately overvalued, although the cost in trade might be reasonable as a result.
As for Smyly, this is a guy who relies on command and control, and he was able to do that well in his rookie campaign. He's left-handed and primarily throws a fastball, cutter and slider. He's a flyball pitcher and was hurt by the home run ball last year and extra base hits in general - 40 percent of the hits he allowed were for extra bases. But Smyly's repertoire is similar to that of Jon Niese and there's clearly some upside at a low short-term cost, making him an intriguing player to consider.
