After acquiring Chase Headley from the San Diego Padres on Tuesday, Brian Cashman admitted that he has more work to do before the July 31 non-waiver trade deadline.

"I have more work to do," Cashman said. "I'm going to still continue to try to improve on what we have. I feel like I've got more work to do."

Cashman indicated he negotiated with the Arizona Diamondbacks for over a month to land Brian McCarthy, and three weeks for Headley.

"We've got high-end stuff, without a doubt, players that other teams like," said Cashman. "And those players would be available, or will be available, in the right circumstances. These are the deals that I can present to you that we were able to conclude, but we're talking much larger type deals, clearly much smaller, incremental upgrades."
