"Everybody is dealing with something, and I'm dealing with something," Darvish said.
Darvish lasted just 5 1/3 innings on Tuesday night, and has now pitched 204 innings on the season. He is scheduled to start on Sunday against the Angels.
"Now that I've thrown over 200 innings, I've done the minimum of my job," Darvish said. "There are still games to play and I'd like to pitch as many innings as I can."
Darvish spent two weeks on the disabled list in July with a strained trapezius muscle in his shoulder and missed one start. But his 204 innings are the 14th most in the American League going into Wednesday.
"Everybody has issues, his are no different," manager Ron Washington said. "The grind of a Major League season is like no other grind anywhere else."
