The player to be named was named Tuesday: Lester Oliveros, right-handed reliever who had a brief stint in the majors earlier this year but has spent most of the season in the minors. He's 23, has good strikeout rates in the minors and some command issues. The Twins saw him twice during his call-up, July 22 and 23.
As a member of the Tigers' 40-man roster, he had to go through waivers before he could be sent to the Twins.
Oliveros entered the season ranked by Baseball America as the Tigers' 17th best prospect; Cole Nelson, the lefty in the deal, was listed as No. 30.
Basically, the Twins added to their bullpen inventory with this trade. They didn't clear a spot on the 40-man roster, because Oliveros replaces Young on the 40.
