The Philadelphia Phillies have placed Carlos Ruiz on the disabled list with a strained right hamstring.
Ruiz has a Grade 2 hamstring strain. He has played in 16 games and is hitting .235 with two RBIs.
"Right now he'll probably be out three to four weeks -- relative time frame," Phillies trainer Scott Sheridan said. "That's kind of what we're thinking right now based on the size of the tear and location."
