For starters, when Oakland A's designated hitter Khris Davis was first scouted when he was a seventh-round draft pick by the Milwaukee Brewers out of Cal State Fullerton in 2009, they weren't too keen on his base-running and fielding ability. "He never ranked higher than 13th on the Brewers' Top Prospects list, but that one tool got him to the big leagues and resulted in 133 homers in his first three seasons in Oakland before he tailed off this year," Callis and Rosenbaum write.
