The Royals signed Lopez to a minor-league contract Wednesday.
Lopez will backfill the Royals' organizational middle-infield depth after Andrew Velazquez was called up to grab Bobby Witt's (back) roster spot. The 30-year-old Lopez had been at Triple-A Tacoma in the Mariners organization, where he slashed .302/.379/.419 with two home runs and a 13:10 BB:K in 43 games. He hasn't played in the majors since 2023.
