Drafted in the C-A round (35th overall) by the Milwaukee Brewers in 2008 (signed for $1,010,000).

Frederickson was climbing draft charts late as he put together a pair of his strongest starts of the year to finish the season. Several scouts were on hand as he battled San Diego's Brian Matusz in his penultimate start, and Frederickson struck out 11 in seven shutout innings of his last outing, against Dallas Baptist. Some scouts say Frederickson, at an imposing 6-foot-6, 238 pounds, has better stuff than Dons lefty Aaron Poreda, the White Sox's 2007 first-round pick. They both have lower arm slots, and while Frederickson doesn't reach the high 90s as Poreda can, he does have a plus fastball, touching 95 and at times sitting in the 91-93 range. His slider gives him a weapon Poreda never had; it's a power pitch, a hybrid slurve that has some depth and is thrown in the low 80s. When it's on, he makes lefthanded hitters look bat. Command is never going to be Frederickson's forte, and he flirts with having "the thing" at times; he was awful (6.99 ERA) in his first two seasons at Virginia Tech before finding the plate more under the tutelage of San Francisco pitching coach Greg Moore, though his delivery still has flaws. Scouts view him as a reliever, but perhaps more than just a lefty setup man. He could go as high as the second round.

Frederickson moved dramatically up the Brewers' draft board after he attended a workout in Milwaukee a few days before the draft and stunned the scouts on hand by throwing in the high 90s with regularity and ease. Figuring he might be a late bloomer, they grabbed him with the 35th overall pick and signed him for $1.01 million. After he got to low Class A, they soon were reminded why he wasn't rated as highly before that workout. He has a tendency to be wild--very wild, in fact. Frederickson went through a dead-arm period and totally lost the strike zone at times, walking 26 hitters and throwing 10 wild pitches in 20 innings. He struggled though similar issues at Virginia Tech for two years before transferring to San Francisco. The big-bodied Frederickson's mechanics elude him at times. He's at his best when commanding his breaking ball, a slurve thrown from a three-quarters arm angle in the low 80s. When he throws it for strikes, lefthanders have no chance. It's too early to determine a role for Frederickson, because everything depends on his control. He's the classic boom-or-bust pitcher. If he conquers his command issues, he'll move dramatically up this list.
