This much is clear: Interim skipper Kirk Gibson will be a part of that decision.
Webb, who hasn't pitched since Opening Day 2009 and underwent shoulder surgery last summer, will meet Monday with new general manager Kevin Towers. Pitching coach Mel Stottlemyre Jr. and the training staff will also be in the room, Gibson said.
"I have said all along if Webby is ready to pitch in the big leagues, I don't think we would stop him," Gibson said Sunday morning. "Whether that's the case or not, that's what the discussion is about."
Webb said Saturday he didn't believe he needed to be in "midseason form" to compete in a Major League atmosphere.
"Because somebody wants to, we understand that," Gibson said, "but you've got to be ready."
Webb threw about 35 pitches in a simulated game on Saturday and, at the earliest, would be able to throw Tuesday in San Francisco, where the D-backs open their penultimate series.
"He's worked for two years," Gibson said. "It's been a long, frustrating road for him. If it's deemed that it's time for him [to pitch], then he'll do it. If not, then we'll continue on some type of program to make sure that he has an opportunity to do that."
To reinstate Webb, a pending free agent, off of the 60-day disabled list, Arizona would need to clear a 40-man roster spot -- just one more obstacle in the way of the rehabbing right-hander's anticipated return.
