The St. Louis Cardinals will be without one of their core sources of power for the next two weeks after they placed first baseman Brandon Moss on the 15-day disabled list with a left ankle sprain. Moss was in the midst of an outstanding season with a .562 isolated power, 17 home runs and 40 RBIs this season, as he helped propel a Cardinals' lineup that has cored the third-most runs in baseball.

With Moss out of action, the Cardinals have called up outfielder Randal Grichuk. The 24-year-old outfielder was sent down to Triple-A earlier this season and in 15 games has five home runs, 15 RBIs and owns a .283/.291/.623 triple-slash line. Patience at the plate has never been his calling card, even at Triple-A, where he has struck out 13 times and drawn just one walk. Given Grichuk hit just .206 with eight home runs and a 54/18 K/BB rate in 225 plate appearances for St. Louis before he was sent down, it will be hard to trust him even if receives significant at bats while Adams is out.

When Adams returns, he will continue to provide an excellent source of power and RBIs for the Cardinals and fantasy owners, though it's still unknown exactly when he will return. When further updates on his long-term status become available, we will provide it.
