The July 31 non-waiver deadline is less than six weeks away. Do the San Diego Padres know who their general manager is?

Technically, they do — it’s Josh Byrnes. But is Byrnes empowered with the authority to make trades?

Ownership isn’t saying, leaving the front office in an unsettled state.

Well, the Pads need to get their house in order — and fast.

Their trade candidates include not only a number of veterans who could help contenders, but also a starting pitcher with the potential to shake up the entire market — right-hander Andrew Cashner.
If the owners want Byrnes to continue as GM, they should make their position clear. If not, they should dismiss Byrnes and install a replacement as quickly as possible.

The latter scenario is more likely; Byrnes’ relationship with ownership has deteriorated, according to major-league sources.

Assistant GM A.J. Hinch, who has close ties to Byrnes, likely would be the interim successor, sources say.

Byrnes hired Hinch as manager during his tenure with the D-Backs. Both were fired on July 1, 2010, and Hinch joined the Padres’ front office three months before Byrnes’ arrival.

The death of Padres Hall of Famer Tony Gwynn last Monday complicates the timing of any decision; the memorial service for Gwynn will not take place until Thursday.

Firing Byrnes or anyone else would be distasteful while the franchise remains in mourning. But at some point, the uncertainty needs to end.

The Padres’ owners, who inherited Byrnes when they took over in August 2012, seem itchy to make a move, even though Byrnes reportedly is signed through ‘17.

Byrnes mostly has traded well since becoming GM in Dec. 2010. But his free-agent signings and especially his contract extensions often have gone awry.
