DENVER -- Atlanta Braves right fielder Jason Heyward was placed on the 15-day disabled list on Tuesday after an appendectomy.
The team said late Monday that Heyward had surgery at Rose Medical Center in Denver.
Manager Fredi Gonzalez said before the opener of Tuesday's day-night doubleheader against Colorado that there was no set timetable for Heyward's return. The Braves recalled infielder Tyler Pastornicky from Triple A Gwinnett to fill Heyward's roster spot.
Heyward was off to a slow start, batting .121 with two homers and five RBIs. Still, the Braves began the day with a 13-5 record.
"A couple of days ago when we were in Pittsburgh, he felt like he had some stomach fires going," Gonzalez said, "and then it just kept getting more localized, moving to his right side."
Billingsley to have Tommy John surgery
NEW YORK -- Los Angeles Dodgers pitcher Chad Billingsley will have Tommy John surgery this week and miss the rest of the season.
The Dodgers made the announcement Tuesday, a day before the right-hander was set for the elbow operation in Los Angeles. The team said it typically takes about 12 months to return to competition.
Billingsley was 1-0 with a 3.00 ERA in two starts this season. He was scheduled to start last Sunday in Baltimore, but instead was put on the 15-day disabled list because of pain in his elbow.
The 28-year-old injured his elbow last August and decided to try rehabilitation instead of major surgery. He had been pain-free until feeling pain last Friday in a bullpen session. An MRI showed the injury.
Billingsley is 81-61 with a 3.65 ERA in eight big league seasons.
Nationals claim LHP Cedeno from Astros
WASHINGTON -- The Washington Nationals claimed left-handed reliever Xavier Cedeno off waivers from the Houston Astros and optioned him to Triple-A Syracuse.
The Nationals announced the moves Tuesday.
Cedeno was designated for assignment by the Astros last week. He had an 11.37 ERA in five appearances this season for Houston.
Washington only has one left-hander in its major league bullpen, Zach Duke.
Cano denies links to South Florida clinic
ST. PETERSBURG, Fla. -- New York Yankees second baseman Robinson Cano denied any involvement with a South Florida clinic under investigation by Major League Baseball after a report linked an associate of his to the facility.
ESPN reported Monday that the spokeswoman for Cano's foundation is listed as having been a client of Biogenesis of America LLC, a now-closed anti-aging clinic in Coral Gables. She told ESPN she did not receive anything from the clinic and said Cano never did, either.
Yankees third baseman Alex Rodriguez is among the big leaguers linked to clinic. The Miami New Times reported in January it had obtained files showing Rodriguez bought banned substances from the facility. Rodriguez's spokesman has denied the allegations in the New Times report.
Before Monday night's game at Tampa Bay, Cano said he does not feel there is a need to contact Sonia Cruz, the spokeswoman for his foundation.
"It has nothing to do with me," Cano said. "I'm just going to keep playing my game."
Cano said he had not seen the report.
