Before Lester decided to join the Cubs, Boston was considered one of his top destination points. With Lester headed elsewhere, Boston is expected to make starting pitching a top priority for the remainder of the offseason. As it stands right now, Clay Buchholz and Joe Kelly are entrenched at the top of the rotation, with plenty of question marks in the final three spots. Brandon Workman returns after a disappointing 2014 season in which he posted a 5.17 ERA over 15 starts. Twenty-five year old Rubby de la Rosa is coming off a slightly better performance, posting a 4.43 ERA over 18 starts. The final piece is twenty-four year old Allen Webster, who posted a 5.03 ERA over 11 starts.
On the other hand, the Marlins are a team that returns plenty of proven, young arms. Despite top starter Jose Fernandez going down with an elbow injury after just eight starts, the 2014 Marlins' pitching staff had the fifth best WAR in the NL, according to Fangraphs. Fernandez is expected to return from Tommy John surgery at some point midseason, joining a staff that's average age is just 25 years old. It comes as no surprise that the Marlins are interested in Miley, as it was reported early in the offseason that the Marlins were interested in adding another arm.
Miley has spent the past four seasons with the Diamondbacks, making his MLB debut in 2011. Since joining their rotation, Miley has posted a 3.79 ERA over 102 starts. Miley, a 2012 NL All-Star, will enter his first arbitration year in 2015, and will likely land a salary in the $4 million range.
