Sox bring back Miller with one-year deal

With pitching depth the team's greatest need this offseason, the Red Sox signed left-handed pitcher Andrew Miller to a one-year, non-guaranteed contract for the 2012 season, avoiding salary arbitration.

Miller's contract is worth $1.04 million, according to sources. He would receive an additional $50,000 if he makes 20 starts, and another $50,000 if he makes 25 starts. Miller figures to be a candidate to earn a spot in the rotation during spring training depending on what other moves the Sox make this offseason.

Miller appeared in 17 games with the Red Sox in 2011, including 12 starts, and went 6-3 with a 5.54 ERA with 50 strikeouts in 65 innings. The left-hander allowed three runs or fewer in eight of his 12 starts and Boston was 9-3 in those outings. However, Miller's production lagged badly late in the season. His ERA during the infamous 7-20 Septemeber was 11.70, the highest for a Sox pitcher with at least 10 innings pitched in the post-World War II era.

Signed by the Red Sox as a minor league free agent prior to the 2011 campaign, he also pitched in 13 games (12 starts) with Triple-A Pawtucket last season, going 3-3 with a 2.47 ERA with 61 strikeouts in 65 2/3 innings, holding opponents to a .181 clip (42-for-232).
