The Cardinals placed outfielder Ryan Ludwick on the 15-day disabled list Wednesday because of a strained right hamstring and recalled outfielder Nick Stavinoha from Triple-A Memphis to fill his spot on the 25-man roster. Stavinoha will be available for St. Louis' Wednesday night game against the Pirates. Ludwick was pulled out of Tuesday's game in the bottom of the second after trying to chase down a deep fly ball to right-center field off the bat of Nyjer Morgan -- who ended up with a triple. After Ludwick came up short trying to snag it, manager Tony La Russa and head athletic trainer Barry Weinberg went out to check on the 2008 All-Star. After walking around a bit, Ludwick was taken out. The Cardinals currently also have center fielder Rick Ankiel on the DL, retroactive to May 5. Very interesting to say the least, The Cardinals have been hit hard by the same injury bug the Cubs have gotten, with DL-stints for Glaus, Ankiel and now Ludwick.
