Pineiro appears to be at least two weeks away from making his season debut with right shoulder tightness, while Kazmir likely will miss at least two starts with lower back soreness.
"Joel will need at least two rehab [assignments]," Angels manager Mike Scioscia said of Pineiro, his fourth starter. "Depending on where he is today, two weeks is probably the best case [scenario], but it's possible."
The Angels were relieved to hear on Monday that Pineiro was experiencing no lingering pain in the aftermath of muscle tightness in his back near the right shoulder blade.
He left a camp game on March 20 against the Cubs in Mesa, Ariz., after two innings with what was described as muscle tightness in the back near the right shoulder. The veteran downplayed the pain the following day, but he has been unable to cut loose since then.
