The sequence confirmed the blessed fortune shining on the Royals, even as the events hinted at the organization’s darkest fear. In the seventh inning of a 6-4 victory over Minnesota on Monday, Salvador Perez stood inside the dugout with his shirt untucked and his right knee sore. It was his turn to bat. He would not. Instead Erik Kratz, a 34-year-old backup acquired last month, headed to the plate.

“That’s one of the reasons we got him,” manager Ned Yost said. “We knew that he had power.”

Kratz jumped on the first pitch he saw, allowing the team a moment to forget about Perez’s condition. The impact shattered his bat. His power still propelled the baseball over the left-field fence. For good measure, he boomed a second homer in the ninth, giving him his first career multihomer game, and temporarily obscuring the concern over Perez’s knee.

The team phrased the injury as “discomfort” as the game wound down. A club official relayed that Perez was removed as a “precautionary measure.” The Royals listed his availability as “day to day.” Perez missed 67 games after tearing his left meniscus in the spring of 2012.

Perez “pinched” his patella tendon as he rounded second base shortly after his two-run single in the fifth, Yost said. He caught two more innings. As he usually does, he insisted he could play Tuesday at Coors Field in Denver. Yost stressed there was no structural damage to the joint. “Just tight,” Perez said.

The injury sullied an otherwise tidy evening. The Royals (69-55) nabbed their eighth consecutive series victory. Jason Vargas (10-5, 3.17 ERA) extended his streak of scoreless innings to 17 before yielding a solo homer in the seventh. He lasted seven innings in all, allowing only four hits along the way, as his teammates returned to normalcy after an eventful four days at Target Field.

A bothersome outing by Greg Holland mitigated the happiness of Friday’s victory. The offense sputtered on Saturday, then dropped a dozen runs on their rain-soaked foes the next afternoon. On Monday evening, amid another brief shower, the Royals resembled the club that has raced past Detroit in the American League Central.
