The New York Yankees have placed Masahiro Tanaka on the disabled list with right wrist tendinitis and a mildly strained forearm.

Tanaka will be completely shut down for 7 to 10 days and Brian Cashman said he expects the right-hander to miss at last a month of action.

The Yankees are being cautious with Tanaka in part because he missed 10 weeks last season due to a small tear in the ulnar collateral ligament in his right elbow.

"We want to make sure this does not lead to more horrific problems," Cashman said.

Tanaka was superb in his past two starts, but he complained of pain in the side of his wrist Tuesday when he arrived at Yankee Stadium.
