Royals 3, Athletics 0: Danny Duffy threw six innings of one-hit ball as Kansas City evened the series in a rain-shortened game at Oakland.

Duffy (1-0), a 23-year-old lefty, had the Athletics off balance all night, striking out eight and walking four.

There was a 40-minute rain delay before the first pitch and a constant drizzle throughout the game. The downpour picked up with two outs in the top of the eighth, resulting in another delay of more than an hour before the game was finally called.

Aaron Crow was credited with the save for pitching a scoreless seventh.

The Royals got two runs off Oakland starter Graham Godfrey (0-1) in the fourth when Mike Moustakas doubled home Billy Butler, and then Jeff Francoeur scored on a Humberto Quintero sacrifice fly.

Mitch Maier added a run in the seventh with a leadoff homer into the empty right-field seats.

Cliff Pennington recorded the only hit for Oakland, a one-out double in the third.

GAME NOTEBOOK: Royals center fielder Lorenzo Cain made a sensational grab in the second, slamming into the wall and then firing to first for an 8-4-3 double play … The Royals' two-run fourth ended a streak of 25 scoreless innings at Oakland-Alameda County Coliseum … Royals starters have combined to allow only five runs in 30 innings.
