Baker: Trading for a player to help fix Nats' bullpen woes not an option

At this rate, maybe the Washington Nationals would be wise to call up Jonathan Papelbon.

After entering the top of the ninth inning with a 3-1 lead, reliever Shawn Kelley surrendered a game-tying home run to Aaron Altherr followed by back-to-back doubles. The Philadelphia Phillies went on to win 4-3.

It was Kelley's second blown save of the year, and the team's seventh this season.

As the Nationals continue to struggle to close out games, manager Dusty Baker was asked afterwards what the next move would be and admitted the team's current struggles puts them in a precarious situation.

"You can push for a trade, but there ain't nobody trading right now," Baker said, according to Mark Zuckerman of MASN Sports. "We have to look from within right now."

Entering Sunday, Nationals relievers have combined to post a 5.18 ERA, fourth highest in all of baseball. The closer position has been a topic of conversation all year. Blake Treinen was first to earn the role out of spring training, but has struggled immensely, posting an 8.10 ERA.

Kelley has since taken over, and after Sunday's performance, his ERA is up to 7.15 in 13 games.

Starter Gio Gonzalez, however, offered support to his relievers despite their struggles.

"I trust each one of those guys in the pen," he said. "I want Kelley back out there again."

The Nationals lost former closer Mark Melancon in the offseason, who went on to sign a four-year, $62-million contract with the San Francisco Giants, and also struck out on other closers in free agency.

One potential option is David Robertson of the Chicago White Sox, as the club was rumored to be interested in the 29-year-old prior to the season, but talks reportedly broke off some time ago.
