While Arraez has stepped up, one of the few problems I see for the Twins is their lack of capable replacements in the minors. Cave is a big-league player, but besides him there isn't a player in Rochester capable and deserving of promotion to the majors IMO. Injuries are going to happen and I don't anticipate the lineup suffering much because of the current bench--Gonzalez, Astudillo, Arraez and Adrianza--they are big league players (we'll need a little bigger sample size with Arraez) and they are versatile. On the pitching side, other than hoping for lefty to emerge from Meíja, Vasquez or Moya, no one has jumped out at Rochester. Meíja hasn't started a rehab yet and the other two have not been effective. Maybe one of the AA arms can help, but in a pennant race, I wouldn't want to rely on rookies. The top prospects have not fared well on the whole, with a large number of them being injured (both pitching and position). Package some of them for pitching help? I guess I'd say go for it. There will be a lot of potential free agents after this season, including three members of the rotation. To me, this looks like a time to go for it.
