Lewis experienced the issue when making a leaning jump deep into the right-center-field gap when attempting to track down a fly ball from Sean Murphy in the eighth inning, which wound up going for a game-tying double. Lewis landed upright, with most of his weight pushing down on his left foot, before pausing and firing a throw back into second base once the run had scored.
The center fielder remained in the game for the final out of that frame, then he was replaced when the club returned to the field in the top of the ninth by Jarred Kelenic, who moved over from left.
Lewis suffered a bone bruise in the same knee during Spring Training that forced him to miss the first 17 games of the regular season. He also tore the ACL in his right knee shortly after he was drafted in 2016, which wound up requiring a lengthy road to recovery.
“The ball that Murphy hit over his head or in the gap there in the eighth inning, he kind of reached for it, and I think when he came down, he felt some soreness in his knee,” Mariners manager Scott Servais said. “A little bit similar to maybe what he felt in Spring Training. He did miss some time with that, so just precautionary. Let's get him out of the game. Let's get a checked on and take a look from there. So again, we'll wait and see.”
The Mariners went on to rally in the 10th for a walk-off win, but Lewis’ spot in the lineup was filled by Jack Mayfield, who scored the game-tying run.
The setback comes at a time where Lewis is heating up at the plate and looking much more like the player that took the Majors by storm at the start of his award-winning 2020 season. He went 1-for-4 on Monday with an RBI double in the fourth inning, raising his season slash line to .246/.333/.392 to cap off a stellar May, when he led the Mariners with a .368 on-base percentage.
