Royals right-hander Jason Hammel, likely the team's No. 3 or 4 starter, tossed 5 1/3 strong innings, and prospect Ryan O'Hearn doubled and homered.
Hammel didn't give up a hit until there was one out in the fifth inning, when catcher Devin Mesoraco singled sharply to left-center. Hammel gave up one run, walked one and struck out five. He threw 76 pitches, 57 for strikes.
O'Hearn doubled in the Royals' run in the fourth inning, a shot into the right-field corner that scored Paulo Orlando, who had singled.
O'Hearn, the Royals' No.
