ATLANTA -- Cardinals left fielder Matt Holliday has been activated from the 15-day disabled list and is starting against the Braves on Saturday.
Holliday had been out since July 12 with a strained right hamstring.
The Cardinals optioned outfielder-first baseman Brock Peterson to Triple-A Memphis to clear a roster spot for Holliday.
Holliday has a .268 batting average with 13 homers and 47 RBIs. Peterson, who was recalled from Memphis when Holliday was placed on the disabled list, had one hit in seven at-bats.
