Mariners: Virginia 3B Steven Proscia. Solid performer on college baseball's No. 2 team, solid power and arm strength are his best tools.

Diamondbacks: Montana HS OF Ben Roberts. He's a rare prospect from Montana. Boise State wanted him as a wide receiver, and he's a quality athlete with very raw tools. 

Nationals: Notre Dame RHP Brian Dupra. One of the draft's better senior signs, he finally had success at Notre Dame this year. His fastball sits at 90-92 mph and reaches 95, and his slider has improved.

Cubs: California HS 1B Trevor Gretzky. The son of the Great One was thought to be bound for San Diego State, but that might change after he got drafted this high. Power is his best tool, but the rest of his game needs a lot of work.

Athletics: South Dakota State RHP Blake Treinen. He's a rare prospect from South Dakota. His fastball sits at 92-94 mph and touches 97, and he shows flashes of a plus slider. He'll probably be fast-tracked as a reliever.

Tigers: Wichita State LHP Brian Flynn. Huge-bodied (6-8, 239 pounds) lefthander who touches 95, a description that always attracts scouts. He's not very consistent, but his improved slider increases hope that he can figure it out. Draft-eligible sophomore.

Blue Jays: California HS 2B Christian Lopes. He looked like a first-rounder early in his high career, but his tools haven't developed as hoped. Instead of becoming a multitooled shortstop, he's more of an offensive second baseman.

Cardinals: Kansas State OF Nick Martini. An OBP machine who reached base in an NCAA Division I-record 93 straight games, he has a nice lefty swing and solid speed. His bat is his only plus tool.

Red Sox: Kansas HS LHP Cody Kukuk. He's a projection lefty who's a long ways from being a finished product, but he already touches 93 mph and shows the makings of a hard slider.

Padres: Ohio HS RHP Matt Wisler. Easily the top high school prospect in Ohio, he has shown a low-90s fastball and promising breaking stuff.

Rangers: Georgia HS C Max Pentecost. He had Tommy John surgery in April, but he's a catcher with offensive potential and athleticism. 

Giants: Pittsburgh RHP Raymond Black. He can hit 97 mph and flash a plus slider, but he has had limited success. Relief prospect.

Rays: Gonzaga LHP Ryan Carpenter. He went backwards after a strong summer in the Cape Cod League. At his best, he's a four-pitch guy with an 89-92 mph fastball.

Phillies: Yavapai (Ariz.) JC RHP Kenny Giles. He hasn't pitched a lot, but his fastball creeps up to 99 and he also has a high-80s slider and a splitter. Relief prospect.
