So what was the topic?
"I've got no comment on what we were talking about," Yost said.
Half-joking, a reporter asked if Brewers officials were deciding which prospects to send to the Indians for everybody's favorite on-the-trading block pitcher, C.C. Sabathia.
"I've got no comment on that," Yost said.
It does not take a detective to know the Brewers have been discussing the market for a starting pitcher, even though the current five have been holding the fort. The Brewers lost Yovani Gallardo to a knee injury that likely ended his season, and the organization is relatively thin on potential replacements at Triple-A Nashville.
Sabathia is not the only target reportedly on Milwaukee's radar. Veteran San Diego right-handers Greg Maddux or Randy Wolf -- whose bags were in an outer room of the visitor's clubhouse at Chase Field on Thursday, waiting for a weekend series between the D-backs and Padres -- also could make sense as short-term rentals for Milwaukee. San Francisco's Matt Cain and Kansas City's Zach Greinke have been mentioned in published reports, but Melvin said those pitchers were more likely candidates to be dealt in the offseason.
Melvin would prefer to do something sooner rather than later, especially if he's dealing for a starting pitcher who only works every five days. He's hoping other teams are of the same mindset.
"Teams may be willing to move now because maybe they can get more," Melvin said. "It's all a waiting game."
Yost is understandably hesitant to say whether his club needs outside help. And Brewers starters are among the best in the National League, ranking sixth of 16 teams with a 4.18 ERA.
"I will say this: In Atlanta, we always had the mentality that you can never have enough pitching," Yost said.
He would not say much beyond that.
"I don't look outside of my clubhouse," Yost said. "I don't 'long' outside the clubhouse. If someone comes in here to help us over the next couple of weeks, I'll welcome them with open arms. ... Doug does a great job of taking care of us."
The way Melvin sees it, that the Brewers are involved in so many rumors is a sign that the franchise is finally considered a contender.
"We wouldn't be hearing [rumors] if we weren't in this position," Melvin said. "We're in a position now to be considered. I said this the other day, that it's nice to be able to talk about it."
He added: "You still have to be careful."
