IMO, the Sox will still consider getting a vet starter . One factor will be the strength of Wright's knee situation. It may be intermittent or like Pedey's , chronic problem all year. Johnson and Velazquez did do well for limited innings vs the Angels who sucked pretty much the last several games, until they met the Orioles last night.
Assuming that the last 3 games (at Fenway) with NYY are critical to the AL East win, Cora will have fun juggling the last two weeks to get Sale, Price and Porcello lined up just right to win it. I wouldn't trust Erod, Wright , Johnson or Velazquez with one of those games if they were critical.
