The San Diego starting rotation has seen a lot of change over the course of the season, a lot of which has to do with injuries. Michael King has had two stints on the IL while Yu Darvish missed the first half of the season recovering from elbow inflammation.
On the non-injury side of things, Dylan Cease has had a massive drop-off in production, while Randy Vásquez was sent down to the minor leagues. Ryan Bergert and Stephen Kolek were solid when filling in for King, but both were traded at the deadline to the Royals in exchange for catcher Freddy Fermín.
