Keep one of Pineda or Odorrizi. Sign one of the five best free agents, they have plenty of money. Trade for someone, I couldn't list a specific name, but there will be a decent or good pitcher traded this off season. I can't guarantee it is better than this year, but you can't not sign anyone and go with four rookies. It also isn't realistic to expect them to sign three good free agents, as some have suggested. No team has ever done that. This front office chose to have this problem, by not singing anyone or trading for anyone, and it isn't an easy one to fix.
