#12 prospect in the Cardinals organization
From MLB:
An Illinois prep standout taken in the second round of the 2011 Draft, Tilson is proving that perhaps it is not how you start, but how you finish. After missing his first full season with a shoulder injury, the speedy outfielder has put himself back on the map, including a 2015 season that saw him lead the Texas League in hits and stolen bases.
Speed is indeed Tilson's best tool and it can serve him well both on the basepaths and in center field. He improved in terms of his basestealing skills in 2015, but the Cardinals would love to see him become even more aggressive, which they think will help him cut down on his caught stealing rate. Tilson has a good idea of what he's doing at the plate, albeit without power. He draws walks, drops down bunts and uses the whole field. With more experience, he has the chance to be a tick above-average in center field defensively, though right now he still outruns mistakes he makes with his jumps and routes. He has a below-average throwing arm.
Tilson may profile best as a valuable fourth outfielder, though there's still a chance he can be a top-of-the-order catalyst and everyday center fielder.
