Capellan was a key piece of the Brewers' relief corps in 2006, making 61 appearances and posting a 4-2 record with a 4.40 ERA. However, he was optioned out to Nashville at the end of Spring Training and requested a trade soon after. He was placed on the restricted list later in April after leaving the team for two days, but has had a clean record since.
Cody is in his second year with the organization, having been an eighth round pick in last year's draft. This season he has split time between West Michigan and Lakeland, and has looked pretty good despite a 5.6 overall record; In 15 starts he has a 1.89 ERA and has struck out 95 batters to only walking 16.
Capellán is only three years older than Cody, and has already seen a good amount of time coming out of a Major League bullpen. With that in mind, this may not be a bad move for the Tigers, who should try anything in their power to use Jason Grilli less.
UPDATE - 1:30 pm:
Danny Knobler has chimed in on the deal. He seems to like it.
