HOUSTON -- With 12-plus seasons and more than 1,500 games under his belt, catcher Brian McCann has earned the trust of the Houston coaching staff to declare himself ready for reinstatement from the 10-day disabled list without the benefit of a rehab assignment.

McCann, who has missed nine games with right knee soreness, will be activated by the Astros (77-49) for the series finale against the Washington Nationals on Thursday. McCann was placed on the disabled list Aug. 14, his second stint on the DL this season -- he missed seven games in late May with a concussion.

With his production in a steady decline for roughly two months, McCann might benefit from the break. His OPS hit .860 on June 18 and began to drop immediately thereafter. He is batting .120 this month and his OPS for the season has slipped to .720, his lowest since April 6.
