STAMFORD, Conn. -- Brian Cashman dressed as an elf, rappelled down a building and stole Santa's bag of toys back from the Grinch Sunday night at the Heights and Lights Christmas event.

He had his cellphone in his pocket the whole time.

"I made a lot of deals on the practice rappel [Friday], so I guess people are waiting for me to make deals today," Cashman said, still in costume before leaving for San Diego for baseball's winter meetings. "I'm trying. I had to have my phone with me. See?"

Friday's deals, of course, netted the Yankees shortstop Didi Gregorius from Arizona and lefty reliever Andrew Miller. What deals could fall into place in the hours after Cashman participated in the actual Heights and Lights Christmas event?

"We'll see. Waiting," he said.

The Gregorius deal, which sent Shane Greene to Detroit, took the Yankees out of the shortstop market. But they're still interested in bolstering a bullpen that already includes Miller and Dellin Betances.

Cashman said Miller's 2015 role is not yet set.

"I think it's going to be determined based on how the rest of the winter shakes out with our bullpen," Cashman said. "If I do some more additions, then I think it'll declare itself better how he best fits. I'm not done yet, so we'll see."

Former Yankees closer David Robertson is still an option, but Cashman wouldn't say much more than that.

Cashman also wouldn't say much about Chase Headley, other than the Yankees are still looking at him as a way to improve the lineup.

As for the rotation, Cashman just traded away Greene, who started 14 games in 2014. The Yankees' four best starters still under contract -- Masahiro Tanaka, CC Sabathia, Michael Pineda and Ivan Nova -- all missed significant time in 2014.

"We'd like to add to [the rotation] even though we just subtracted from it," Cashman said. "So we'd like to add to the starting rotation if possible, but it's easier said than done."

Free agent Brandon McCarthy, who posted a 2.89 ERA in 14 starts for the Yankees after a midseason trade with Arizona, could still be in the mix.

"Like every free agent, he wants to maximize his value and probably tuck himself in behind the [Max] Scherzers and the [Jon] Lesters and the [James] Shieldses," Cashman said. "When those guys sign, I think he'll really determine what real market value probably is."

Cashman will arrive in San Diego Monday morning. "We're trying to find ways to make good things happen," he said, "but we'll see."
