Manuel, 26, made his major league debut this season for the Cincinnati Reds, pitching 4.1 scoreless innings, allowing 5 hits, a walk, and striking out two. Most of his year was spent in AAA, where he posted a 2.88 ERA over 65.2 innings, recording 49 strikeouts and allowing 16 walks. This came after a breakout 2008 where he managed a 1.25 ERA over 86.2 innings, primarily in AA.
Since signing as an undrafted free agent in 2005, Manuel has a 2.88 career ERA (funny how numbers work out that way...) over 368.1 innings, with a career K:BB of 339:66. The high strikeout rates should help him in Fenway, and the low walk rates will help anywhere.
Manuel is likely to be a back-of-the-bullpen option, while the Red Sox see if they've found a bargain who can translate his good minor league performance into success in the majors.
Also mentioned in the article is that the Red Sox have finished their 40-man roster movements by adding Manuel.
