The Mariners have shipped right-handed starter Doug Fister and righty reliever David Pauley to the Tigers for outfielder Casper Wells, infielder Francisco Martinez, left-hander Charlie Furbush and a player to be named later.
"The acquisition cost for a starting pitcher is very high right now, as you can see from the trades being made around the majors. There were times where I didn't think we would get a trade made," Detroit general manager Dave Dombrowski said.
"Seattle was looking for some offensive help, and they liked Casper Wells a great deal, and they also liked Charlie Furbush, so those were names that were in this early on. We've probably talked 25 times in the last week."
