Overrated: Anibal Sanchez
Sanchez made the most of his deadline trade from the Marlins to the Tigers, putting up a 3.74 ERA in 12 starts post-trade before allowing just four runs and 14 hits in 20.1 innings of work in three postseason starts for a 1.77 ERA.
He's always been a solid pitcher, with a 3.75 career ERA. But he is reportedly seeking a six-year, $90 million deal, and perhaps even more, according to a tweet from Jon Heyman. In a pitching market thin on top flight guys, he may well get it too.
Underrated: Shaun Marcum
Acquired from the Blue Jays prior to the 2011 season, Marcum went 20-11 with a 3.60 ERA in 54 starts with the Brewers over the past two seasons.
Arm problems limited him to just 21 starts last season, as he missed all of July and most of August, but he returned for eight starts to close out the season and pitched well. There is certainly some injury risk; he did miss all of the 2009 season with Tommy John surgery.
However, he made 31 starts in 2010 and 33 starts in 2011 and when healthy he has frontline starter potential. The red flags will be enough to drive his price down, though, and he could wind up as one of the top performers of the class.
