You've gotta feel for Detroit right-hander Anibal Sanchez.

He was cruising toward a no-hitter against the Minnesota Twins Friday night. It was the ninth inning, two outs to go, the count was 1-1 on Joe Mauer.

If you think all the twitchy rhythms and random shards of melody flashing through Stravinsky's The Rite of Spring sound complicated, consider the poor musicians who have to learn it. And then there's the conductor, who needs to perfectly place every piccolo tweet and bass drum boom.

In his national security speech Thursday, President Obama discussed drone warfare and the Guantanamo detention camp. But a third controversial issue went largely unmentioned: the use of interrogation methods that are tantamount to torture.
