The Mariners are not a team with too many openings this season after a busy off-season that saw them bring in Casey Kotchman, Ryan Garko, Milton Bradley, and Chone Figgins to be parts of the everyday lineup. Still there is the potential for youngsters to crack the lineup as the season progresses particulary in left field, first base, and at catcher given the fragility of Milton Bradley, the lack of power of Kotchman, and the non-offense and off-season surgery for Rob Johnson.
The upper levels of the St. Louis Cardinals system experienced tremendous change in 2009 with ten rookies making their MLB debuts while five players from the first two rounds of the 2006 through 2008 amateur drafts were traded away to acquire Mark DeRosa and Matt Holliday.
Welcome to my regular column on the minors. During the pre-season I am going to focus on each organization’s prospect depth with a strong focus on those players who will have an impact on the 2010 and 2011 seasons. 2011 because this will be the focus of those clubs rebuilding and/or teams looking to stash players to trade to other teams that have more of a 2011 focus. I am going to include all those players who still have rookie status.
