There isn't a whole lot of certainty about what the Mariners' starting lineup for the 2012 season will look like. Yes, Felix Hernandez will be on the mound and Dustin Ackley will probably play at second base, but we can't take much else for granted.
It's likely that Manager Eric Wedge will keep the starting lineup relatively similar to the one we saw at the end of the 2011 season, but we'll definitely get some surprises as spring training rolls around in March.
The lack of consistency in the structure of last year's lineup coupled with the lack of consistency in a lot of players currently on the roster equates to a much-increased chance that some hot prospects will hit the bigs on Opening Day.
Obviously, there isn't room for 10 prospects to be called up, but a few of the players in the minor league system have a shot at making the cut come April.
Here's a look at the 10 prospects on the Mariners who have the best shot at making the 2012 Opening Day roster in order of increasing likelihood.
(If a player has had fewer than 50 AB or IP in the majors, I'm going to consider him a prospect since a stint that short is really only a closer look for management.)
