5:41pm: Neither Miley nor Borchering is involved in the trade, tweets Piecoro.
5:22pm: Arizona may also send left-hander Wade Miley to Oakland along with Parker and Cowgill, tweets Susan Slusser of the San Francisco Chronicle. The Snakes selected Miley in the supplemental first round in 2008.
As well, the D'Backs made minor league corner infielder Bobby Borchering available during the Winter Meetings, according to Piecoro, though he's not sure if the 21-year-old is part of this potential deal (Twitter).
4:20pm: A D'Backs source says the two sides are still "talking names" and that nothing has been finalized, tweets Piecoro, who adds that it does sound like something is close.
4:02pm: The deal is Cahill and Craig Breslow in exchange for Parker, Collin Cowgill and other prospects, tweets Ken Rosenthal of FOX Sports. Rosenthal says the trade is still "fluid" so more names could be involved.
3:42pm: The Diamondbacks are "closing in" on a trade with the Athletics that would send Trevor Cahill to Arizona in exchange for a prospect, reports John Gambadoro of Sports 620 KTAR in Phoenix (Twitter link). Gambadoro says the prospect isn't Trevor Bauer or Tyler Skaggs (Twitter links).
We heard yesterday from Ken Rosenthal of FOX Sports that Cahill had been mentioned in talks between the D'Backs and A's. Gio Gonzalez's name also came up between the two teams, with Rosenthal noting that the Snakes would need to deal Skaggs to get Gonzalez, but Cahill could be had for a lesser price. Nick Piecoro of the Arizona Republic mentioned yesterday that "it's believed that [the D'Backs] focus" was on Cahill and mentioned Jarrod Parker as a candidate to go to Oakland in the swap.
