The Boston Red Sox signed right-hander Justin Masterson to a one-year, $9.5 million deal Thursday night.
Masterson opted to sign a one-year contract after having his worst season in 2014.
The 29-year-old was originally selected by the Red Sox in the second round of the 2006 draft before being dealt to Cleveland for Victor Martinez in July of 2009.

The Red Sox also recently added right-hander Rick Porcello in a trade with Detroit and lefty Wade Miley in a trade with Arizona, further strengthening their rotation.
