Oliver, 25, was drafted by the Tigers in the second round in 2009. He was once pretty highly-regarded and had a taste of the Majors, but in 2012 his Triple-A walk rate soared to 6.7 per nine innings. Baseball America has described him as "a power lefty who needs to throw more strikes." Oliver had a dust-up with the NCAA in '08, winning a lawsuit against them after he was suspended for having an adviser in talks with the Twins.
Cabrera, 23, spent most of 2012 in Double-A, hitting .276/.342/.367 in 428 plate appearances. He's a high-contact switch-hitter with a questionable arm, wrote BA.
