The New York Yankees and Washington Nationals discussed a trade involving Dan Haren last weekend but never got close to a deal, according to sources.

Brian Cashman declined to confirm the talks, but didn't deny that he has continued to seek upgrades as the American League Wild Card race continues.

"We haven't stopped trying to improve," Cashman said. "We've always been open to different things, pursuing different things. It started all the way back in March, when all the injuries hit."
