The St. Louis Cardinals placed outfielder Matt Holliday on the 15-day disabled list Saturday with a hamstring strain, according to Fox Sports' Ken Rosenthal. The team will promote Brock Peterson from Triple-A Memphis in a corresponding move.
Holliday left the Cardinals' game against the Chicago Cubs on July 11 in the fourth inning after clutching his right leg while running out a grounder. He has not appeared in a game since suffering the injury.
The 33-year-old slugger was left off the All-Star squad for the first time since 2009 after hitting .268/.351/.448 with 13 home runs thus far this season. That's good for a 122 OPS+, but is a significant drop from the production that Holliday usually provides. He has also grounded into a league-leading 22 double plays in 83 games, nearly surpassing his previous career-high of 23.
Holliday played in at least 155 games in five out of the last seven seasons, but won't reach that total in 2013. The 10-year big-league veteran is a lifetime .310/.385/.531 hitter with 242 career home runs.
Peterson, 29, will get his first taste of big-league action after spending 11 seasons in the minor leagues. Peterson has posted a .306/.382/.564 line with 22 home runs in 390 plate appearances for Memphis.
