Red Sox avoid arbitration with lefty Morales

The Red Sox have agreed to terms on a one-year contract with pitcher Franklin Morales, thus avoiding salary arbitration with the left-hander.

Morales, 25, split last season between Colorado and Boston, and he finished the year 1-2 with a 3.69 ERA in a career-high 50 appearances out of the bullpen.

The southpaw has spent parts of five seasons in the big leagues -- with the Rockies from 2007 until May of '11, when he was acquired by the Red Sox.

Morales also set career marks for innings pitched (46 1/3), strikeouts (42) and holds (10). He held opponents scoreless in 28 of his 36 appearances out of Boston's bullpen.

Morales is 8-12 with 10 saves and a 4.61 ERA in 138 career Major League games.
