The Padres have invited their major league coaching staff to return intact for 2014.

“There are still some details to work out but we want everyone to return” Padres general manager Josh Byrnes said Wednesday night before the Padres routed Arizona 12-2 in the penultimate home game of the 2013 season.

The Padres last winter picked up the options on the contract of manager Bud Black for the 2014 and 2015 seasons.

Black’s staff includes pitching coach Darren Balsley bench coach Rick Renteria hitting coaches Phil Plantier and Alonzo Powell third base coach Glenn Hoffman first base coach Dave Roberts and bullpen coach Willie Blair.

Balsley and Hoffman were already in their present roles with the Padres when Black became the manager at the start of the 2007 season.

“One of the strengths of this organization is the coaching staff” Black said recently.

Wednesday night the Padres scored four runs with two out in the bottom of the fifth to break a 2-2 tie before 29528 at Petco Park.

The big hits were a two-run single by Chris Denorfia and an ensuing two-run homer by Jedd Gyorko.

The beneficiary of the Padres biggest show of offense in 43 games was right-hander Ian Kennedy who evened his record against his old team at 1-1.

Rookie first baseman Tommy Medica drew the Padres even at 2-2 in the fourth with his third homer as a Padre and his first at Petco Park -- a 411-foot drive into the sand beyond the fence in right-center.

“We got a little spark when Tommy went into the sand with his homer” Black said.
