The Detroit Tigers' rotation will be absolutely loaded in 2013.
The Tigers boast the best pitcher on the planet in Justin Verlander and three 28-year-old hurlers in the prime of their careers.
Max Sherzer, Doug Fister and the newly re-signed Anibal Sanchez are terrific complements to Verlander and will be part of one of the toughest rotations to face next season.
But the Tigers have an issue with their No. 5 starter.
After the Tigers re-signed Sanchez, it became almost inevitable that Detroit would look to trade struggling right-hander Rick Porcello.
Porcello began his career with Detroit in 2009. After being a first-round draft pick in 2007, the young right-hander came to the Tigers with elevated expectations.
But after four years donning the Old English D, Porcello hasn't lived up to expectations. After being pulled from Detroit's postseason rotation last year, the Tigers are reportedly shopping the 24-year-old.
Here are the four reasons the time is now for the Tigers to trade Porcello.
