"I honestly believe that," Mattingly said. "I know there's a lot going on and a lot of talk about it. And again, I think it's an area that, to really say that that's not getting a hit with runners in scoring position or making a pitch with a guy in scoring position or any of that ... I think it's just not true."
The Dodgers entered their Interleague series against the Twins with a 35-44 record, sitting 9 1/2 games behind the first-place San Francisco Giants.
Left-hander Clayton Kershaw, like his manager, sees no correlation between the off-field issues and the on-field play.
"I really don't think so," Kershaw said. "You see the guys in this room, you see guys like Matt [Kemp] and Andre [Ethier] and James [Loney] is hitting really well right now ... we've got all the pieces. And that's almost the frustrating part is that we're not just stringing the wins together like we should.
"But I definitely don't think what's going on out there is resulting in a poor team on the field. I think we've got good players. We should be playing better than we are, and the good news is we're not quite halfway there yet, so we've still got a shot."
Mattingly and Kershaw both noted that an e-mail from Peter Wilhelm, the Dodgers' chief financial officer, was forwarded to everyone on the team, letting them know the club would continue to operate as usual within the organization.
Kershaw said that as a team, they "definitely like to focus on baseball," and that he hopes the whole situation will be figured out soon.
"I think that's what everybody wants, whether it's Mr. McCourt or baseball or us. Everybody wants it just to be settled," Kershaw said. "That's kind of what everybody's going for, it's just everybody has differences of opinion on how to get there."
