"I'm sure it could get done over the phone, from my perspective," said Cashman, who is completing a three-year, $6 million agreement with the club. "I don't want to speak for him."
The Steinbrenners have ranked bringing Cashman back among their top offseason priorities, and team president Randy Levine offered Cashman a vote of confidence near the end of the regular season.
Cashman said that he will be occupied this week in New York. The Yankees are holding their professional scouting meetings -- a first step to determining the course of their offseason, after a disappointing five-game loss to the Detroit Tigers in the American League Division Series.
"We've got all our scouts coming in, and we're going to get after it for at least three days, starting Wednesday here in New York," Cashman said. "Obviously, Hal and I will talk via phone, and we'll get whatever we need to get worked out, I'm sure, between now and Oct. 31st."
Cashman said that his expiring contract has not affected how he attacks his offseason duties -- which will, no doubt, include efforts to clear up ace CC Sabathia's contract situation.
Sabathia has until three days after the World Series to opt out of his contract, tearing up the remaining four years and $92 million on his deal. Cashman said that he expects to have discussions with Sabathia's representatives in the near future.
"I'm sure we'll talk before the World Series is over," Cashman said.
Last weekend, one of Sabathia's agents, Brian Peters, told ESPN.com that "we will exhaust all of our efforts to reach a new agreement" with the Yankees and added, "CC has been clear about how he feels about New York and the Yankees."
Cashman said that he is also keeping an eye on the Angels' unsettled GM situation, with lieutenants Billy Eppler and Damon Oppenheimer both having been granted permission to interview for the vacancy.
Eppler, 36, has served as the Yankees' senior director of pro personnel since 2009, reporting directly to Cashman. The 48-year-old Oppenheimer has overseen the turnaround of New York's farm system as the vice president of amateur scouting.
"Obviously, we have two people interviewing with the Angels that carry key positions for us," Cashman said. "You have quality people and you have quality people behind those quality people. Just like a farm system on the field, you're supposed to have depth.
"That's why you train people. In the event you lose somebody, you have somebody, hopefully, there that's qualified and hungry to take the places. We'll see. I'd rather not be in that position. But if we are, we'll be forced to deal with it."
