They didn't need four arms. Nobody believed they would catch KC and it would have taken more than four bullpen arms anyway. They needed one other guy, someone better than Jepsen, as well as Jepsen himself. It would not have cost them any of the guys listed above. Berrios isn't going to be harmed or stunted by being in the pen from August on. He's going to face major league hitters and get a taste of what he's in for, a chance to acclimate. He wouldn't be the first highly regarded pitching prospect to start in the bullpen. If the Twins do that, it's likely that gong show in NY doesn't happen and neither does today. This bullpen was trouble from day 1, professional baseball people should have been able to recognize that.
