When the Yankees placed reliever Adam Warren on the 10-day DL Saturday, they did so with the understanding he'll be shut down that entire length of time. Aaron Boone said the mild right back strain will shelve Warren longer than those 10 days. Warren said this was more an issue of discomfort rather than a pain issue. He felt it during his past couple appearances, but figured he could play through it. Could feel it a little more Friday night while throwing his off-speed pitches.
