t started with a double by Alex Gordon, gained momentum on a single by Eric Hosmer and another double by Billy Butler, and then was capped by a two-run shot from Lorenzo Cain. It was a four-run eighth inning by the Kansas City Royals. It was the kind of outburst that hasn't happened often. In this case, it carried the Royals to a 7-3 victory over the Minnesota Twins on Thursday night and to back-to-back wins for the first time since May 4-5. But the big inning also represented as many runs as the scuffling Kansas City offense had produced in any of its last 14 games.
