Boston Red Sox right-hander Ryan Dempster plans to take this season off, a decision that will cost him $13.25 million in salary.

He said Sunday he's stepping away for physical reasons and to spend more time with his family.

"I had an incredible run, a chance to play 16 years in the major leagues," Dempster said a day before the first formal workout for pitchers and catchers in Fort Myers, Fla. "I'm totally comfortable with it. I'm at peace with my decision."

He finished his only year with the Red Sox with an 8-9 record and a 4.57 ERA and didn't get a start during their postseason run to a World Series title.

"I've got three amazing children that I want to watch grow up and be around," Dempster said.

What about 2015? "I don't know yet," he said.

  • Atlanta and All-Star closer Craig Kimbrel agreed to a $42 million, four-year deal with a $13 million team option for 2018 and a $1 million buyout. Kimbrel, 25, had 50 saves, a 1.21 ERA and 98 strikeouts in 67 innings last year. He avoided arbitration.

  • Mark Mulder described his season-ending -- and possibly comeback-ending -- left Achilles injury as a freak accident. Trying to return to the big leagues for the first time since 2008, Mulder was doing warm-up drills when he heard a pop Saturday.

    "I thought the heel popped out of my shoe. I felt like the ball of my foot wasn't attached to my foot," said Mulder who signed a minor league deal with the Los Angeles Angels and was invited to spring training. As for the future, the former A's left-hander said he's "going to meet with the doctor (Monday)."

  • A.J. Burnett and Philadelphia completed a contract that guarantees the pitcher $22.5 million over two seasons.
