Triple-A Buffalo reinstated Danner (undisclosed) from the 60-day injured list Wednesday.
Danner missed two months while recovering from an undisclosed injury, but he finished up a rehab assignment with Single-A Dunedin on Aug. 10 and has pitched well in two relief appearances for Triple-A Buffalo. The right-hander has allowed one unearned run on one hit while walking two and striking out three over two innings.
