Jose Cisnero is the one to be moved
With the emergence of Kyle Funkhouser as an effective reliever, he could be a good setup man to Gregory Soto and have either a combo of Joe Jimenez and whoever else to pitch the seventh inning. The Tigers could call up veteran Drew Hutchison from Toledo to fill the role in the rotation or pitch long relief.
The one problem with this idea to trade Cisnero is Buck Farmer has been too inconsistent and Alex Lange has struggled. You could insert Jason Foley and see what he is capable of so that is another option.
So the question becomes who would be a good fit for Cisnero among the contenders? The Red Sox do need bullpen help and Toronto, who is in fourth place, has had their bullpen destroyed by injuries as they nine pitchers on the IL.
Would a lefty like Anthony Kay be an option for Detroit to pick up? He was pitching out of the bullpen for Toronto before being sent back down to Buffalo. Kay is on their 40-man roster and features a fastball, curve, and a changeup.
The Giants out west could use another veteran bullpen arm as they try to hold off the Dodgers in the NL West race. Even the Padres could also use another vet arm to load up.
Cisnero is 32 years old and his value is never been higher. Detroit could get something useful in return to patch at least one of the holes on this roster.
The Detroit Tigers are playing well and the results speak for themselves but as they head towards August, if they can make just one move to help make them still competitive without losing Jonathan Schoop, this could be the answer.
