KANSAS CITY -- Royals shortstop Alcides Escobar left Sunday's 2-1 loss to the Mariners after the sixth inning because of a bruised left shin.
Escobar was struck in the leg by left-hander Roenis Elias' pitch in the second inning, but he remained in the game. Escobar played four more innings before being replaced by backup infielder Pedro Ciriaco.
"It just swelled way up and got real sore on him," manager Ned Yost said. "He went as far as he could. He's a tough kid. It got him right in the shin. When I went down and looked at it, he had a big knot on it."
X-rays taken at Kauffman Stadium were negative and Escobar's availability is considered day to day, but he has not missed a game this season. Escobar planned to play on Monday night against the Dodgers.
"I'll be ready, you know me," he said.
