Upton, Chamberlain stand out among prospects

SAN FRANCISCO -- Some notes from the scouts' section behind the plate Sunday at AT&T Park.

Top Five Hitters

1. Justin Upton, CF, Arizona Diamondbacks: Not even close. Upton was a man among boys, even though he's just 19 years old. He's a fast-twitch hitter, like his brother, B.J., who lets the ball travel deep and then just spins his whole body to whip the bat through the zone. He centers the ball well and showed enormous pull power in BP and in the game, when he crushed a 91-mph fastball out to left. He has a plus arm, 60 on the 20-80 scale, but threw a couple of rainbows to the plate because his footwork was off -- a fixable problem.

2. Jay Bruce, RF, Cincinnati Reds: He's going to strike out some, and I think he'll show a platoon split, but he has some enormous raw power of his own, turning on a 95-mph fastball for a triple to the triangle in right-center. He has a 60 arm as well and will be fine in right field.
