With Dexter Fowler out of commission after suffering a wrist strain, the Cardinals have promoted top prospect Harrison Bader to take over center-field duties. Bader had been crushing Triple-A pitching to the tune of .297/.354/.517, though those numbers are inflated by the run environment of PCL. In his big-league debut last night, Bader doubled and scored the winning run.
Even after accounting for the effects of the PCL, Bader has hit for a healthy amount of power this year, belting 19 homers in 97 games. There’s more to Bader than his power, however. Eric Longenhagen rated him as a 60 runner, which parlays into good baserunning and center-field defense — Clay Davenport’s numbers consistently have him above average in center.
Bader profile isn’t all roses and sunshine, as his strikeout and walk rates both leave much to be desired. These metrics suggest he may have issues getting on base in the majors. Eric also voiced concerns about the prospect of Baders’ swing working against major-league pitching.
Bader has plus bat speed and some raw power, but it’s hard for him to utilize it in games because his swing is so flat and linear. He has to really adjust his lower half to move his barrel up and down in the hitting zone and, while this worked at Double-A, not everyone thinks it’s sustainable in the big leagues. Additionally, Bader has trouble seeing the ball against right-handed pitching, especially breaking balls, over the top of which he often swings. It’s more of a 40/45 hit/power profile which doesn’t play everyday in a corner, but Bader was an above-average runner for me in the Fall League and plus during the season for some scouts with whom I spoke, so some orgs think he can moonlight in center field.
No outlet has ranked Bader in their top 100, presumably for the reasons Eric laid out in his write-up. But my KATOH system disagrees with this assessment. My system pegs Bader for 5.7 WAR over his first six seasons by the stats-only method and 4.5 WAR by KATOH+, which incorporates his prospect ranking. Those marks place him 61st and 73rd, respectively, among prospects.
To put some faces to Bader’s statistical profile, let’s generate some statistical comps. I calculated a Mahalanobis distance between Bader’s 2017 performance and every season since 1991. 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.
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.

Bader his flaws, but he also has a lot going for him. Most notably, he’s a 23-year-old who’s now succeeded at the highest level of the minor leagues. Sure, his numbers were helped by the PCL. But even if this year’s numbers are largely smoke and mirrors, Bader remains a speedy center fielder with power and passable defense. Those can be quite valuable.
