Lewis (knee) will take batting practice on the field during the Mariners' current homestand, which runs through Sunday, Daniel Kramer of MLB.com reports.

EDGE Analysis

Lewis has recently been taking part in baseball activities, but the batting practice will be his first on-field work since landing on the shelf in late May. The 26-year-old remains without a timetable for his return, though manager Scott Servais is confident the outfielder will take the field again this season. Lewis will need to continue ramping up his rehab work before embarking on what could be a lengthy rehab assignment.
