I'm all for putting some of the starters in the pen, but looking back at the best starter-turned-reliever transitions, they almost all took a full season to get their footing and establish themselves.
I wanted Clippard. I'll still take Norris, Madson and Warren, Kimbrel too. I'm not too keen on Vincent, I don't trust relievers who throw 89 MPH.
I do like the Blake Parker signing, I think he would have been one of the higher under-the-radar guys I would have been in on had he been a free agent to open the year. But if he's not throwing a slider or changeup, he probably needs to throw that curve more. I'd think he'd need better diversity than running with a four seamer and splitter 90% of the time.
I would be pretty disappointed if the Twins traded for bullpen help considering this near historic class of free agent relievers; that would scream of choosing money over prospects.
