Remember that blue silence? Yeah, neither do the Royals, who own a season-best five-game winning streak after sweeping the Houston Astros from town with a 2-0 win Sunday at Kauffman Stadium.

Notice that it didn’t take four runs, either.

The Royals tagged Houston reliever Hector Ambriz for the game’s only two runs during the decisive eighth inning, sending the crowd of 20,723 home happy.

“Great pitching and defense today,” said left fielder Alex Gordon, who broke the scoreless deadlock with one-out RBI single in the eighth. “It kept us around long enough to do some damage there in the eighth.”

Luis Mendoza matched Astros starter Lucas Harrell with seven shutout innings before the Royals won a battle of the bullpens.

Mendoza stranded runners in each of the first three innings, including the third when he worked around a leadoff double by Ronny Cedeno, with help from a few defensive gems.

Third baseman Mike Moustakas opened the game with a diving stop on Jose Altuve’s line-hugging grounder and center fielder David Lough followed with a diving catch on Jason Castro’s sinking liner.

Shortstop Elliot Johnson, who was playing on the right side of second base as the Royals shifted for pull-happy Carlos Pena, added a diving stop in shallow center on a grounder up the middle for the final out in the first inning.

Buoyed by the sterling plays behind him, Mendoza and catcher Salvador Perez found a rhythm from there, retiring 15 of the next 17 Houston batters.

“That gave me a lot of confidence just to throw pitches right to Salvy’s mitt,” Mendoza said. “I was confident and it helped me make a lot of quick outs.”
