In their search for starting pitching, the Tigers had discussed a trade with the Rockies for Ubaldo Jimenez, but general manager Dave Dombrowski eventually made a deal with the Mariners for Doug Fister. The 27-year-old righty sports a 3-12 W-L record, plus a 5.49 K/9, 1.97 BB/9, and 3.90 xFIP in 146 innings. Right-handed reliever David Pauley will join Fister in Detroit.

In return, Seattle will receive reserve outfielder Casper Wells and minor-league southpaw Charlie Furbush. Third-baseman prospect Francisco Martinez is reported to be included in the deal as well.
