Kenley Jansen says his condition has improved since he was diagnosed last month with an irregular heartbeat and the Los Angeles Dodgers closer is aiming to return to action next Tuesday.
"I've just been trying to stay in shape and stay sharp," Jansen told MLB.com. "I'm feeling great.
"I could go out and pitch today if they needed me but I can't. I've got to get off the blood thinner first. That's how good I feel."
Jansen last pitched Aug. 27 when he got dizzy and felt his heart accelerate. He was diagnosed with atrial fibrillation and was placed on a blood thinner because of a risk of blood clots.
Two days after he comes off the thinner he'll be eligible to pitch.
SORIANO MAY BOLT YANKS
Yankees reliever Rafael Soriano may use the opt-out clause in his contract to leave New York after this season, CBSSports.com reported Thursday.
Soriano has the option to stay with the Yankees for a $14-million salary in 2013 or take a $1.5-million buyout.
Sources say Soriano is leaning toward taking the buyout and signing with another team. He would prefer to be a closer somewhere else rather than be a setup man for Mariano Rivera, who is expected to return from knee surgery next season.
In Riviera's absence, Soriano has converted 37 of 40 save opportunities and has a 2.17 earned-run average. The 32-year-old right-hander could command a lucrative salary in free agency.
REUTERS OWNER DENIES SOX FOR SALE
Boston Red Sox principal owner John Henry denied a report Thursday that he was selling team,
Fox Business Network reported that the Red Sox could be going up for sale because the ownership group couldn't afford to own both the baseball team and Liverpool FC of the English Premier League.
"A sale of any kind is so far from our thinking it hasn't even come up apart from technical planning issues involving death or disability," Henry told the Boston Globe.
Henry's Fenway Sports Group bought the Red Sox in 2002 and Liverpool FC in 2010.
ASTROS' HUNT BEGINS
Washington Nationals third base coach Bo Porter on Thursday was the first to interview for the job as manager of the Houston Astros, MLB.com reported.
Porter, 40, also has been a coach with the Arizona Diamondbacks and Florida Marlins.
General manager Jeff Luhnow intends to talk with as many as eight candidates, including interim Astros manager Tony DeFrancesco.
Brad Mills, who played third base for the Montreal Expos during the early 1980s, was fired as manager on Aug. 18.
New York Yankees pitcher Andy Pettitte, 40, will start Tuesday against the Toronto Blue Jays, the team has announced. It will be the left-hander's first appearance since June 27, when his left ankle was broken by a line drive from the Cleveland Indians' Casey Kotchman ... Oakland Athletics outfielder Yoenis Cespedes left Thursday's game against the Los Angeles Angels with a sprained right wrist. Cespedes was hurt in the fourth inning when he slid into second base.
