"If it's me, I'll just try that much harder to get right back up here," said Jered Weaver. "That's the way it goes."
Black said there's no obvious choice of who will be demoted.
"Everyone is throwing the ball well," he said. That includes Jered's older brother, Jeff, who has a 3-8 record but has won two of his last three decisions.
The younger Weaver has given up just four earned runs in his three starts, striking out more opponents (17) than he has allowed to reach base (15).
The club has made it clear that should Jered be moved out the rotation, he will head back to Salt Lake rather than work out of the bullpen.
