Minor Moves: Nate Robertson, R.J. Seidel

Here are today's minor moves of note:

• The Tigers have brought back lefty Nate Robertson on a minor league deal, reports Jason Beck of MLB.com (via Twitter). Now 36, Robertson spent five years as a mainstay in the Detroit rotation between 2004-08, but has not pitched in the bigs since 2010. Last year, in 50 1/3 Triple-A innings with the Rangers organization, Robertson put up a 3.04 ERA with 7.2 K/9 and 4.1 BB/9. 
• The Brewers have released righty R.J. Seidel, tweets Chris Cotillo of MLB Daily Dish. The 6'5" Wisconsin native posted a 4.64 ERA in 75 2/3 innings and whiffed more than a batter per inning at the Triple-A level last year. The 26-year-old has spent his entire career in the Brewers organization since being a 16th-round draft pick in 2006. Last season was the first time Seidel's strikeout rate has climbed to that level; he's punched hitters out at a rate of 6.8 per nine in 521 minor league innings.
