The Red Sox announced that they designated right-hander Chris Carpenter for assignment. The move creates roster space for Mike Napoli, whose one-year deal is now official.
The Red Sox acquired Carpenter as compensation for Theo Epstein last February. The 27-year-old pitched in eight games for Boston this past season, allowing six earned runs in as many innings. He also pitched at the minor league level, posting a 2.08 ERA with 10.4 K/9 and 4.2 BB/9 in 21 2/3 innings. Carpenter missed time to undergo surgery to remove bone spur from his right elbow in 2012.
