Most of these "scouting reports" are from amateurs, so take them with a grain of salt.
I watched the players, Haseley is solid in CF, lacks great speed, but gets a good jump, and a solid arm. As a hitter was too eager at first, but really worked counts well the last month or so of his rookie season, hits to all fields and has a legitimate shot at being a .300 BA hitter.
Hoskins as a hitter is his own worst enemy, when he struggled he started over swinging and chasing pitches, we'll see if he gets back on track this year. Like Howard, he's best when he hits to the opposing alley (Right center) b/c he has park power in every direction. Gets in trouble when he gets pull happy.
Howard was an upside pick, didn't start many college games, 14 which is less than Haseley. 124 IP. So he was as much a projection off of his frame and his feel for secondary pitches as actual scouting.
Bohm should at the least be as good fielding as Franco, which if he hits, will be good enough, though it suggests that a fielding upgrade at SS is in the team's future.
