Tigers sign Octavio Dotel

The Tigers signed Octavio Dotel to a 1 year 3 million dollar contract with an option year of 3.5 million with a $500,000 buyout. I will assume here that they will buy him out, so the contract is 3.5 million. Dotel had a .6 WAR in 2011 (a 5833 WASP with the new contract) and a .7 WAR average over the past 3 years (a 5000 WASP). He had a -4.04 PE and -4.31 Adjusted PE in 2011, so in that sense he pitched like one of the elite relievers in baseball. He had the lowest WHIP he had since 2003, but also had his lowest BABIP since 2005. However, he also had his lowest FIP since 2002, so its not like he was just really lucky. He pitched really really well. His TR also reflected that with a 10.42, along with a SIERA of 2.67. He did throw the lowest amount of pitches since 2007, but with no that could simply be how he was used. On the other hand, 54 innings (his 2011 total) is hardly a large sample size. The HR/9IP rate as well as the groundball rate are things that do concern me. Comerica Park can somewhat mask those rates, and Dotel has shown that those rates aren't that important as he has been dealing with them his whole career. Although this is more than I like to pay for relievers, this deal might not be bad at all.
