Fernando Rodney sets single season record for lowest ERA in MLB History. Named 2012 MLB American League Comeback player of the Year
At 35 years old, Rodney also made his first All-Star game in 2012 and is among the favorites to win the 2012 American League Cy Young Award (although I think it will go to his teammate, David Price).
MLB has announced their Most Improved Player since 2005. Cliff Lee is the only pitcher to win both the MLB Comeback Player of the Year and Cy Young awards in the same season (2008). Mike McCormick won both the Cy Young and TSN Comeback Player of the Year (not an official MLB award) in 1967.
