The San Diego Padres mortgaged their future for 2015, but have disappointed and are currently on the outside of the National League playoff picture.

Buster Olney of ESPN writes that A.J. Preller can partially restock the club's farm system, which was nearly emptied in trades for Matt Kemp, Craig Kimbrel, Justin Upton and Wil Myers, by selling ahead of the July 31 non-waiver trade deadline.

With so many teams in the race the market is expected to be thin in the coming weeks, something the Padres can capitalize on.

"The Padres wouldn't have to execute the course shift right away, but the sooner the better, because the expectation among GMs is that by July 20, more and more teams will jump in as sellers, and San Diego's pieces wouldn't look quite so exclusive," Olney writes.
