Kontos (elbow) is scheduled to pitch with Triple-A Sacramento on Sunday, Alex Pavlovic of CSN Bay Area reports.
It was unclear whether Kontos would head straight to the Giants or pitch in a rehab assignment, but it appears that the Giants have decided to go with the latter. The right-hander said that his elbow feels great, and although the Giants want him to make another rehab appearance afterward, he seems to be very close to returning to the San Francisco bullpen.
