SAN DIEGO -- The D-backs' front office left the Winter Meetings without having made any moves, but they did make headway in determining how their players are valued by other teams and what it will take to land certain free agents.

Now, they return to Phoenix to sort through it all, with a move for another reliever likely to come first.

They continue to receive inquiries about outfielders Jake McCarthy, Daulton Varsho and Alek Thomas -- Corbin Carroll is not available, teams have been told -- and it still seems likely they will part with one in order to add a significant right-handed bat to their lineup.

They also have talked to the A's about catcher Sean Murphy, though Murphy is in high demand throughout the game at the moment.

BIGGEST REMAINING NEEDS

1. Bullpen arms
The D-backs added a trio of pitchers before the Meetings in Carlos Vargas, Cole Sulser and Miguel Castro, but they are still looking to add to that part of the roster, with general manager Mike Hazen saying they still have one or maybe two relievers left to nab.

2. Right-handed hitting
This is where the young outfielders come in. With all four being left-handed hitters, the D-backs would like to add a little more balance to the lineup. In order to do that, they will likely have to part with one of the outfielders. Where that right-handed bat would fit in remains to be seen. It could be a catcher, like Murphy, or it could come in the form of a third baseman, second baseman, or shortstop.

3. Starting pitching depth
This is much further down the list than the other two. The D-backs have a host of young pitchers like Tommy Henry, Ryne Nelson, Drey Jameson and Brandon Pfaadt penciled in to compete for a pair of spots in the rotation, but Hazen is still apt to sign some depth at the spot. He has told agents of some pitchers that the D-backs have interest but need to take care of other spots on the roster first.

RULE 5 DRAFT
The D-backs heard a rumor before the Major League portion of the Rule 5 Draft that Triple-A Reno outfielder Dominic Canzone was going to go first overall, but in the end, Canzone did not get selected.

"He's a good player, a good hitter," Hazen said. "So it adds to our stable of guys that are coming to Spring Training. We have a lot of left-handed hitters, but we're happy to keep him and we really like him."

GM'S BOTTOM LINE
"I think things have become much more specific," Hazen said in terms of what possible deals he could pull off. "We've exchanged more specific names on players. We have enough specificity around some of these that I feel like we'll have to have some decisions to say yes or no."
