Bobby said Kawakami will make one more start before any decisions are made….

when i asked if he hurt his chances for staying in the rotation, Cox said, "We are not making any decisions right now," Cox said. "He’s got another start to go before we have to do something."

This actually tells me the decision is already made...he's just going to fill the void until JJ comes back which will be either the 29th or 30th against Washington and possibly Stephen Strasburg.
