The Tigers will not pursue free agent-to-be Cliff Lee or another top tier free agent starter this offseason, tweets MLB.com's Jason Beck. That does not mean they will only go after back-of-the-rotation starters, however.
Detroit already boasts a frontline starter in Justin Verlander, and Max Scherzer has been outstanding (153.2 IP, 2.46 ERA, 9.25 K/9) after a brief demotion to the minors in May. Those two and Rick Porcello are the only guys guaranteed spots in the Tigers rotation next year, but reliever Phil Coke will reportedly transition to starting according to John Lowe of The Detroit Free Press. Other internal option include Armando Galarraga and Andy Oliver.
The free agent market offers plenty of help beyond Lee, with quality second tier options like Hiroki Kuroda, Jorge de la Rosa, and Ted Lilly. Aaron Harang, Jon Garland, and Bronson Arroyo might also be available depending on whether or not their options are exercised.
