Last season we heard a great deal about the Royals’ next All-Star prospect, Mike Moustakas. Fantasy owners, especially in keeper leagues, were delighted for his call-up to the bigs in mid-June last year. However, Moose didn’t pan out the way everyone hoped. He finished his 2011 MLB campaign with a not-so-stellar .263/.309/.367 slash line with 26 runs, five homers and 30 RBI (mind you, four of those homers came in the month of September). Could the tide be turning for the Moose?
Now, fantasy experts have Moustakas being taken in the late rounds or falling to the waiver wire. Let’s dig in and see what we can expect from the Royals’ 2012 starting third baseman.
Moose was the second pick in the 2007 MLB June Amateur Draft by the Royals and ranked ninth on Baseball America’s Top Prospects list heading into 2011. He spent parts of five seasons in the Kansas City minor league system, playing in 439 games. In his minor league career, Moose slashed a line of .282/.337/.503 with 84 dingers, 21 steals and 335 RBI. The Moose got loose in three of his minor league seasons, hitting over 20 long balls three times and over 30 once.
So, what went wrong with Moose’s 2011 MLB campaign after he put up very respectable numbers in the minors? His walk rate of 6.9 percent in the minors, although lower than one would want to see in a hitter, translated to a 6.0 percent rate in the majors while his strikeout rate decreased since his call up (17.0% to 14.0%). His .296 BABIP was not overly impressive and could improve this year, but that wouldn’t be the telling factor. His HR/FB rate was an abysmal 4.2 percent, leading to just five homers in his shortened MLB campaign. With a HR/FB rate that low and a fly ball rate of 41.2 percent, one could only expect more long balls. His 20 percent line drive rate should translate to a better BABIP, too.
The best way to predict Moustakas’ future in the majors would be to compare him to his cross-diamond counterpart who traveled a similar path to the show, Eric Hosmer. Hosmer impressed with a .293/.334/.465 slash line in his rookie campaign with the Royals, stroking 19 long balls and driving in 78 runs in an up and coming Kansas City lineup. Here’s a comparison of the two future stars’ minor league statistics:

While Hosmer hits for a better average and gets on base more often, the thing that stands out to me is the power numbers. Moose has a higher slugging percentage, albeit not by much, and much higher AB/HR rate and RBI/GM rates. Then, when you compare the MLB HR/FB rate, one could only expect Moose’s major league numbers to rise tremendously and possibly surpass Hosmer’s in 2012.
Moose’s Strengths
Power potential, position stability, lineup and high line drive rate. Moose can hit the ball hard on a line in every at-bat, which eventually will translate to higher totals in his power game and batting average. With a higher BABIP, this guy could hit .290 with 25 homers. He’s surrounded by a young and upcoming Royals lineup but has the comfort of staying in his position (unless we see an Adam Dunn-like collapse). He has the potential to hit at least 20 homers in 2012.
Moose’s Weaknesses
Speed and experience. Moose has a ton of potential, mainly in the power columns, however, having potential to succeed or surpass expectations also means expectations are probably low and there is potential to fail miserably. While Moustakas could hit 20-plus long balls and drive in 80-plus runs, he will not stand out in any category (especially steals with just 21 stolen bases in 439 minor league games). His inexperience is also cause for concern, as he could easily take a downturn and head back to the minors if the Royals choose to do so.
Prediction
.278/.333/.498, 20 HR, 77 RBI, 58 R, 4 SB
I have high hopes for Moose, and I’m going out on a limb and say he’ll be a top 10 third baseman this year. Third base could be one of the weakest positions, especially given how reliant the strength of the position is on the health of some historically injury-prone players, and if you can scoop the Moose up in the late rounds (especially in keeper leagues), why not take the chance on him? Save your draft picks early on, invest in other positions and take a shot on Moose. I know I will.
