It's no secret that the Miami Marlins want to win now, and are seeking to upgrade their pitching staff before the Aug. 1 trade deadline.

But a major problem hangs over their head: Do they have enough prospects to entice a trade partner?

According to Joel Sherman of the New York Post, the Marlins' lack of talent in their farm system is holding them back from making any major moves to get the pitching they desperately want.

"[Marlins owner] Jeffrey Loria is willing to do anything to win today, but there is nothing in their system," an MLB team executive tells Sherman. "I really feel like they could make 13 players available, and I don’t think we would do a deal with them."

While the Marlins have struggled to make a deal, the Chicago Cubs have reaped the benefits of a fruitful farm system, trading four players to land coveted New York Yankees closer Aroldis Chapman on Monday.

The Marlins have been linked to several pitchers in recent days, including the San Diego Padres’ Andrew Cashner, the Arizona Diamondbacks’ Shelby Miller and the Philadelphia Phillies’ Jeremy Hellickson. Sherman writes that Miami has also shown interest in Yankees right-handers Michael Pineda and Ivan Nova.

Meanwhile, another name on the Marlins' radar is Wade Miley, Clark Spencer of the Miami Herald reports. The Seattle Mariners have reportedly been "quietly shopping" the left-hander.

With starter Wei-Yin Chen hitting the disabled list Monday due to an elbow strain, Miami's need for pitching is now even more important. The team is 53-46 this season and right in the thick of the wild-card hunt.
