Image 1 of / 9 Caption Close Image 2 of 9 Alex Jackson, catcher Height/weight: 6-2, 210 School: Rancho Bernardo High School, San Diego, Calif. Pros: Considered the best high school hitter in the draft, he is athletic with tremendous power. A power hitter who is a potential middle-of-the-order guy. He has a plus arm, and scouts think he could play third base, right field or catcher. Cons: Scouts are not sure if he is going to stay at catcher. Some wonder if he eventually will be a corner outfielder. less Alex Jackson, catcher Height/weight: 6-2, 210 School: Rancho Bernardo High School, San Diego, Calif. Pros: Considered ... more Image 3 of 9 Tyler Kolek, RHP Height/weight: 6-5, 270 School: Shepherd High School Pros: Kolek is an overpowering righthander. He has a 100-mph fastball that has drawn comparisons to Nolan Ryan and an imposing frame that reminds folks of Roger Clemens Cons: History is against him because no high school righthander has gone first overall in the baseball draft. Still a bit raw. less Tyler Kolek, RHP Height/weight: 6-5, 270 School: Shepherd High School Pros: Kolek is an overpowering righthander.

Cons: At 6-1 and 196 pounds, his slight frame is a concern even though he can hit 96 mph with his fastball and has plus command of three pitches. less Aaron Nola, RHP Height/weight:6-1, 196 School: LSU Pros: Arguably has put together the best college season in the ... more Photo: Bruce Newman / Associated Press Image 5 of 9 Image 6 of 9 Carlos Rodon, LHP Height/weight: 6-3, 234 School: North Carolina State Pros: Appears closer to the majors than most prospects. His fastball sits between 90-96 mph, and an impressive slider is his calling card. Built impressive résumé as freshman and sophomore. Cons: His repertoire this season hasn’t matched previous years. less Carlos Rodon, LHP Height/weight: 6-3, 234 School: North Carolina State Pros: Appears closer to the majors than most ... more Photo: Mark Crammer / Associated Press Image 7 of 9 Jeff Hoffman, RHP Height/weight: 6-4, 192 School: East Carolina University Pros: With a 97-mph fastball, the 6-4 righthander rose up many draft boards after an impressive showing in the Cape Cod League last summer. Electric stuff and athletic with a plus curve and solid changeup. Cons: Until a couple of dominant starts in April, he had been unable to consistently duplicate his Cape Cod dominance in college. less Jeff Hoffman, RHP Height/weight: 6-4, 192 School: East Carolina University Pros: With a 97-mph fastball, the 6-4 ... more Photo: James Nielsen / Houston Chronicle Image 8 of 9 Brad Zimmer, CF Height/weight: 6-5, 205 School: University of San Francisco Pros: A potential five-tool center fielder, Zimmer is a lefthanded batter who runs well and is having a really good season. Cons: At 6-5, the big slugger might not project as a center fielder in the majors. Size may eventually push him to right field. less Brad Zimmer, CF Height/weight: 6-5, 205 School: University of San Francisco Pros: A potential five-tool center ... more Image 9 of 9 Photos: Seven prospects the Astros are eyeing with No. 1 pick in draft 1 / 9 Back to Gallery
