A Boston Red Sox trade for Miami Marlins pitcher Sandy Alcantara has been floated before, but with the rotation struggling as much as it has, save for Garrett Crochet, the need to add starting pitching has never been greater. The Red Sox don’t have a clear No. 2 starter behind Crochet, and adding such a pitcher should be a priority if this team intends to be buyers at the deadline. Alcantara may be one of the only quality arms available at the deadline this year. The Cardinals looked to have several available arms, but they have also ridden a hot streak into playoff contention.
