KANSAS CITY, Mo. — Talk about carrying some baggage into the season.
Kansas City will be without Salvador Perez for up to six week after the star catcher sprained the medial collateral ligament in his left knee while carrying a suitcase up some stairs in his home.
The injury occurred Tuesday night, when the Royals returned to Kansas City from spring training. The five-time All-Star heard a "pop" and immediately called Royals trainer Nick Kenney, who advised Perez to ice the knee and come in for an MRI exam on Wednesday.
The exam revealed a Grade 2 sprain with a minor tear of the ligament.
No surgery is required, and recovery can be as little as four weeks. But the freak injury leaves the Royals without one of their top hitters when they open against the White Sox on Thursday.
"Hopefully," Royals manager Ned Yost said, "it's shorter than longer."
Perez was wearing a bulky black brace on his knee when he arrived at Kauffman Stadium for the club's final preseason workout Wednesday. Later, he told reporters what irked him most about the injury is it happened at home, rather in the midst of competition.
"All the work I do, training in the offseason, I feel sad," he said.
Making it even more depressing was that Perez, coming off one of the best seasons of his career, had been on a tear throughout the spring.
He appeared in 16 games and hit .350 with six homers and 40 RBIs in only 40 at-bats during the Cactus League schedule.
He hit .268 with career-bests of 27 homers and 80 RBIs last season.
The Royals were counting on having his bat in the lineup after losing run-producers Eric Hosmer and Lorenzo Cain in free agency. And while they addressed some of the power loss by signing outfielder Jon Jay, first baseman Lucas Duda and re-signing third baseman Mike Moustakas — who set the franchise single-season home run record last season — it still hurts to lose Perez's bat.
Yost said after a rainy workout Wednesday that he expects Drew Butera, the club's backup a year ago, and promising youngster Cam Gallagher to share catching duties in Perez's place.
Butera hit .227 with three homers and 14 RBIs in 75 games last season, his third with the Royals, while Gallagher hit .250 with a homer and five RBIs in 13 games as a late-season call-up.
The Royals begin the season against former pitcher James Shields and the White Sox, then get Friday off before games Saturday and Sunday to wrap up a three-game set. Then they go on the road for three games in Detroit and Cleveland before returning home for a seven-game homestand.
