Jackson, who committed single-digit errors in each of the past two seasons at Miami, has been tabbed good enough defensively to play in the Major Leagues today.
"Some of our scouts said that," said Jeff Luhnow, the Cardinals' vice president of scouting and player development. "I think if we sent him to Double-A right now, he wouldn't skip a beat. He'd be able to handle himself defensively without any problem at all.
"In terms of his hands, his quickness and his arm, there's not a lot of guys out there that have his defensive skills."
But while his defense has been spectacular, the junior's offense hasn't been quite as good. Jackson hit just .236 as a freshman in 2007, but he earned All-American honors during his sophomore campaign, when he raised his average to .360 and led the Hurricanes with 19 doubles.
But his sophomore season appeared to be more of the exception than the norm, as he dropped back down to a .263 average with four homers, 38 runs scored and a .362 on-base percentage for Miami this spring.
"It's all about whether or not the bat will be good enough for his defense to make him a valuable contributor for us," Luhnow said. "If we are able to turn him into even just a viable offensive player, he projects to be like an Adam Everett-type defender in the big leagues, so we felt in the fifth round, it was a risk worth taking.
"It's not a no-brainer on how to fix him or how to make him better, but we absolutely think we have a shot at doing it."
Here is a breakdown of the rest of the Cardinals' picks on Day 2:
Round 4, Scott Bittle, RHP, Mississippi: Bittle was 7-1 with eight saves and a 1.78 ERA during his junior year in 2008 and was a second-round pick by the Yankees. But concerns over an injured shoulder kept him from signing, and he returned to Ole Miss for his senior season. Bittle went 5-2 with a 2.17 ERA in 45 2/3 innings, but he missed the last month of this season with more arm troubles.
