Clayton Kershaw soon could become the richest pitcher in baseball history.

But Kershaw was upset that he had to talk Sunday about his ongoing negotiations with the Dodgers, whom he blamed for leaking information to Fox Sports.

The previous night, Fox Sports reported that Kershaw and the Dodgers were "making progress" toward agreement on a seven-year contract extension. According to the report, which cited unnamed "major league sources," the deal being discussed would be worth more than the record $180-million, seven-year contract between the Detroit Tigers and Justin Verlander, who in March agreed to five-year extension through 2019. Exactly how close Kershaw and the Dodgers are to a new deal was unclear.

"I think the reason we've been able to continue discussions for this long is that it's not been talked about," Kershaw said. "And now that I'm having to talk about it, it's a distraction because people are talking about it. I guess you'll have to talk to the Dodgers as to why it came out now. I don't love the fact that I have to talk about it."

Kershaw wouldn't confirm or deny the details of the Fox Sports report, saying he thought he and the Dodgers had a gentlemen's agreement to not speak publicly about the negotiations.

"It didn't come from our side," Kershaw said. "I'm going to still hold up my end of the bargain and not talk about it."

General Manager Ned Colletti declined to comment on the Fox Sports report. Asked to comment on Kershaw's accusation that the Dodgers leaked the story, Colletti didn't respond.

Kershaw is under contract this year for $11 million. He will be eligible for salary arbitration next season, after which he can enter the free-agent market. Dodgers executives have said they would like to have him signed to a long-term deal before then.
