The Rays have designated reliever Dane De La Rosa for assignment in order to clear roster space for Luke Scott. The Pirates have a few open spots in their bullpen, and De La Rosa might well be worth a waiver claim. He turned 30 last week, so he's not a prospect, but he's got size (6'7, 245 pounds) and stuff (he can get into the mid-90s), and his minor-league numbers certainly are interesting -- he's struck out more than a batter an inning all of the last three seasons, and last year, he whiffed 87 batters in 67.2 innings at Triple A.
