"He's confident he can make that start, and that's great, but to get him back in there next week, I think it's best for all of us," manager Dave Roberts said. "I know he's frustrated and I understand that. That's a decision we as an organization have to make. Obviously he's not pleased with it; he feels he can pitch, and I respect that."
McCarthy said he learned Monday he would not be starting.
"Shoulder's fine," McCarthy said. "They're making a decision to work around, a spot to take a breath. They're just playing it super-cautious with the shoulder and just making sure we can build it in with rest. A lot of us with our histories can conserve. If I had my way, I'd be pitching. I was ready to start Saturday, Sunday. With the rainout, they can shuffle things around."
Roberts said McCarthy is limited hitting and fielding by the injury. He said McCarthy will throw a simulated game Wednesday and return to the starting rotation sometime during the club's series in San Francisco next week.
McCarthy is 3-0 with a 3.10 ERA after missing most of the past two seasons. But with Hyun-Jin Ryu and Rich Hill close to returning from injuries, McCarthy is one of the current starters who could lose his job.
Hill, plagued by blister problems, had his rehab start pushed back a day and will pitch Wednesday in San Jose.
The latest diagnosis for outfielder Franklin Gutierrez is that he has a strained hip flexor. Roberts said the club is still hopeful he can avoid a return trip to the disabled list.
