PHOENIX -- Brandon Webb never threw a single pitch for former D-backs manager A.J. Hinch. Whether he will for the club's current one remains to be seen.

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.

Upton to get second opinion on left shoulder

PHOENIX -- D-backs slugger Justin Upton will visit with noted specialist Dr. James Andrews for a second opinion on his irritated left shoulder on Monday.

Upton was traveling to Andrews' offices in Alabama during Arizona's 5-4 home finale win on Sunday. The right fielder hasn't played in 20 of his club's last 24 games and has missed 11 straight starts.

Upton underwent an MRI on his shoulder on Sept. 7, which, according to then-interim general manager Jerry Dipoto, revealed no serious injury.

Upton was removed from the Aug. 30 game after a seventh-inning swing that he said caused the irritation in his shoulder. At the time, both Upton and the club said it was something he had experienced in 2006 and again in 2009 and it would likely be a day or two before he returned.

Upton will rejoin the D-backs in San Francisco on Tuesday for the club's penultimate series of 2010. It's appearing more and more unlikely that he would return to action in the final six games.

D-backs responding to 'nuances' of Gibson

PHOENIX -- Kirk Gibson cringes at the mere thought of being conventional. So the D-backs' interim manager doesn't automatically accept baseball goings-on that counterparts deem customary.

Like, for example, position players leaving the dugout during games to watch replays of their at-bats or to confirm their suspicions of an umpire's poor strike-zone calls.

"Guys were always running back and forth, 'Oh, a pitch was two inches outside,'" said Gibson, who recently revoked access to the video room. "In my opinion, they ran down to watch a negative. I don't like that. The other thing is, I believe you need to be on the bench to watch the game."

How has the adjustment panned out?

"They've been great with it," Gibson said. "Really, it's eliminated a lot of the [complaining].

"I'll continue to try more nuances like that. I think it will help us."

Worth noting

Right fielder Justin Upton (left shoulder irritation) was absent from the D-backs' starting lineup for the 11th consecutive game on Sunday. ... Third baseman Mark Reynolds (right thumb) was also out of the initial lineup for the second consecutive day. Reynolds said he was still sore, had yet to resume batting practice but that he hoped to play this week in San Francisco and/or Los Angeles. ...
