The Oakland Athletics knew they had the potential to be one of the best teams in the majors. They're now putting that talent on full display, and the results have thrust the surging A's to the brink of the best July in franchise history. Yoenis Cespedes and Chris Carter hit two-run homers to back an effective pitching performance by Bartolo Colon, and Oakland beat the Baltimore Orioles 6-1 Saturday night for its ninth win in 10 games.
