Athletics activated OF Josh Reddick from the 15-day disabled list. Reddick wound up missing over three weeks with a strained right knee. He went 9-for-21 with three home runs and eight RBI on his five-game minor league rehab assignment and will try to build off that offensive success in his return to the majors. The 27-year-old outfielder has a disappointing .229/.296/.358 batting line in 54 games this season for Oakland.
