Here are the opening day rosters for the minor league teams. The big story could be the DL, AJ Jimenez, Sean Nolin, Danny Barnes, Chad Jenkins, John Stilson, Tyler Ybarra and Evan Crawford all start the season on the DL.
My first quick look also notes that:
Marcus walden makes the jump to AA after a half season ion Dunedin. I liked Walden last year but AA is a big test for his style of pitching.
Alonzo Gonzalez makes the jump to lansing after a brief debut last season. Gonzalez was a JC selection as was further advanced than the high school pitchers.
Daniel Norris and Roberto Osuna are also starting in Lansing.
Emilio Guerrero beat out a lot of competition to be the shortstop in Lansing.
Chris Hawkins returns to Lansing for a repeat.
I have added more comments at the bottom.
