So I still think we might get a Starting Pitcher.
We have 4 (Wheeler, Nola, Sanchez and Suarez). I still contend we need one more because MOST LIKELY one of them will not be available at the end of the season. Nola has been marginal, Suarez and Sanchez may not be good enough by the end of the season, both have come back to earth in the last 6-8 weeks. Both will be WAY over their career highs in innings by the playoffs.
Turnbull and Walker are probable just possible long relievers in the playoffs.
