Castillo (lat) is feeling much better as he continues to recover, Dennis Lin of The Athletic reports.
Castillo has been sidelined since early July with a lat strain, but manager Jayce Tingler provided an encouraging update on his status Monday. The southpaw still hasn't resumed throwing off a mound, but Tingler said that he remains optimistic that Castillo will be able to pitch for the Padres later in the season.
