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.
Gonzalez said that Heyward had been feeling ill for several days. After Heyward saw a doctor Monday evening, tests revealed the problem with his appendix.
