Before debuting yesterday for Colorado, 22-year-old outfielder David Dahl had recorded a smooth .307/.389/.562 between Double-A and Triple-A this year, including a torrid .456/.508/.886 showing in his short stint at Triple-A. Dahl possesses an exciting combination of power and speed. The former 10th-overall pick belted 18 homers in the minors this year while also swiping 17 bases. Dahl’s 20-plus-homer power is a relatively new addition to his skill set, but it’s not as though he hasn’t shown glimpses of it before.

Dahl has plenty going for him in the power and speed departments, but his strikeout numbers are some cause for concern. He whiffed in 25% of his plate appearances in Double-A last year, and didn’t really improve in that area this season. Much this year’s improvement can be traced back to his sky-high .388 BABIP, while the underlying contact issues linger.

Dwelling on Dahl’s contact rates almost feels like nitpicking, however, especially since his strikeout numbers are trending in the right direction. All in all, Dahl has an awful lot going for him. Whether you look at his stat line or his scouting reports (such as the one published today by Eric Longenhagen), it’s very easy to envision him sticking as a quality everyday center fielder.

My newly revamped KATOH projection system is a big believer in Dahl. My stats-only model rates him as the #12 prospect in baseball, while my KATOH+ model — which also integrates Baseball America’s prospect rankings — placed him at #14. They foresee 9.0 WAR and 11.1 WAR, respectively, over Dahl’s next six seasons.

To put some faces to Dahl’s statistical profile, let’s generate some statistical comps for the powerful center fielder. I calculated a weighted Mahalanobis Distance between Dahl’s Double-A and Triple-A numbers this season, and every season at those levels since 1991 in which a center fielder recorded at least 400 plate appearances. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. A lower “Mah Dist” reading indicates a closer comp.

Please note that the Mahalanobis analysis is separate from KATOH. KATOH relies on macro-level trends, rather than comps. The fates of a few statistically similar players shouldn’t be used to draw sweeping conclusions about a prospect’s future. For this reason, I recommend using a player’s KATOH forecast to assess his future potential. The comps give us some interesting names that sometimes feel spot-on, but they’re mostly just there for fun.

At 47-52, the Rockies clearly aren’t anywhere near the playoff hunt this year. That said, Dahl represents a glimpse into a brighter future for a team that’s spent the last several years shrouded in mediocrity. His swing-and-miss may prevent him from becoming an impact offensive player — at least in the near-term — but there’s plenty there that suggests his long-term future will be a bright one.
