Sources: D-backs trying to deal Upton

Once again, the Arizona Diamondbacks are trying to trade right fielder Justin Upton.

Maybe the third time will be a charm.

The Diamondbacks discussed moving Upton at the 2010 general managers’ meetings and also before the July 31 non-waiver deadline last season.

Ken Kendrick, the team’s managing general partner, told a Phoenix radio station in October that Upton was "highly likely" to return.

Major-league sources, however, say the team is again engaged in active discussions about Upton, and one estimates the chances of him playing elsewhere next season are "80-20."

The Diamondbacks need a shortstop, and Upton possibly could bring them a player such as the Rangers’ Elvis Andrus.

Upton, 25, is signed for $9.75 million next season, $14.25 million in 2014 and $14.5 million in 2015.

His no-trade list last season consisted of four teams: the New York Yankees, Boston Red Sox, Cleveland Indians and Chicago Cubs.

The list has since changed, a source said.

Without Upton — and Chris Young, whom the Diamondbacks traded last month to the Oakland Athletics — the team would still be fairly deep in outfielders.

Gerardo Parra, Jason Kubel and Adam Eaton could form the D-Backs’ outfield next season, with A.J. Pollock in reserve.
