With only two full weeks left in spring training, teams across both the Cactus League and the Grapefruit League are starting to take form as we inch closer to Opening Day. With that said it is back to the batter's box we go in search of who could be a solid late round flier if able to stabilize his spot on his current team. 

Just like in the kitchen, preparation is key to successfully mastering your fantasy draft, with one of the main ingredients being finding value in the later rounds. In most cases we call these players "sleepers," but not all of these players are fresh faces that we have never seen before. In fact, the majority of the players we find in the later rounds we fine aging veterans on the decline, players returning from injury or players who have been up and down between the minor and majors still trying to find a permanent home. Whatever the case may be, these are the players that could be the difference in bringing home the trophy come September. 

Since the term "deep sleeper" can mean a lot of different things, all players discussed in this series will hold an average draft position (ADP) of 250 or higher based off the most recent mock draft results of Fantasy Alarm's own Howard Bender and the Mock Draft Army. If you haven't checked out the Mock Draft Arm series,, be sure to give it a look as Howard continues to assemble some really good ADP information based on a series of mock drafts featuring experts from throughout the industry and fans alike. Now that we laid out the ground rules let's get cookin'...

Dustin Ackley, OF (SEA)

Mock Draft Army ADP: 321.6

Now entering his fifth season with the Mariners, it is clear that Ackley will never be able to live up to the hype place don him after being taken second overall in the 2009 MLB Draft. However, at the age of 27, there is still time for him to solidify a spot in the Mariners everyday lineup if able to work out a few kinks. 

Ackley finished the 2014 season slashing .245/.293/.398 with 14 home runs, 65 RBI and 64 runs scored in his first full season as an outfielder. To his defense, he was drafted as a first baseman out of college, then was converted to play second base before being moved to the outfield a season ago. When you have to worry about learning a new position on almost a regular basis, it can be tough to focus your attention on the offensive side of the game, which has yet to show up as far as fantasy baseball is concerned. 

The one area of his game that hurt is progression a season ago was his inability to draw free passes. In fact, after averaging a solid 9.0 percent rate over the previous three seasons leading up to 2014, Ackley regressed to just under 6.0 percent last year, which resulted in a four-year low .293 on-base percentage. If you aren't hitting for much power in the big leagues, getting on-base is a big factor for players like Ackley, so more patience at the plate will be needed to take the next step forward in his game.

Despite his poor on-base percentage, Ackley did post a career-best 35.9 AB/HR a season ago, which was a major step in the right direction after only hitting four home runs in 384 at-bats in 2013. Even if he never turns out to be the power/speed combo everyone thought he would be coming out of college, there is some room for growth in this area if his ground ball-to-fly ball rate (0.87 in '14) continues to move in the right direction.

Looking ahead to 2015 the Mariners are expected to slot Ackley in the two-hole where he will be sandwiched between Austin Jackson and Robinson Cano, which could lead to solid pitches to hit based on the upside of his teammates. Although this is a rather new spot for Ackley to be hitting, he did finish out the team's last 50 games in the two-hole a season ago, so the adjustment shouldn't be too bad for the 27-year-old.

As long as you don't set your expectations too high, Ackley makes for a solid late-round flier in deep league formats, especially in leagues where he still qualifies at second base. Who knows, maybe he finds his stroke as he is now in the prime of his career, or he falls flat on his face. In the late rounds you really don't know what you are getting, but one thing is for sure, you certainly won't have to pay much for him come draft day.
