The St. Louis Cardinals have placed two players on the injured list and are calling up two from Class AAA Memphis.
Outfielder Tyler O'Neill and right-handed pitcher Jake Woodford are on the 15-day IL. O'Neill has a lower back strain and Woodford is on the list for right shoulder inflammation.
Outfielder Juan Yepez and right-handed pitcher James Naile will replace them on the major league roster.
To make room for Naile on the 40-man roster, pitcher Wilking Rodriguez was moved to the 60-day IL. Rodriguez underwent season-ending arthroscopic shoulder surgery earlier in the week.
This is the second time Yepez has been recalled this season; he previously replaced an injured Lars Nootbaar.
