That gives me an idea to add in a most similar productive player feature for those players with no good comps, or some way of discovering where they might need to improve to give them a better shot. O'Rae is 1.1, -0.83, -0.61, 66.7 So walks a lot, doesn't strike out, has well below average power, and good but not elite game speed (surprising, given his stolen base totals, might be worth a closer look). Billy Hamilton has an 88.7 speed score, Chandler Simpson 76.0.
The closest productive hitter comp he has is Michael Brantley (685 score, which is out of 1000, poor). But he had more power. The only players I can find who had an MLB career wRAA greater than 0 and had that little power in the minor leagues are Esix Snead (14 PA), Yefri Perez (3 PA), and Darren Baker (14 PA).
But Luis Castillo is right there (again, slightly more power, which is crazy, since he had 28 HR in 15 years), but he did have 370 MLB stolen bases and 3 all-star appearances, though I imagine O'Rae's glove isn't at Castillo's level.
