Lewis (knee) was seen running the bases at full speed and sliding in the outfield Sunday, a sign he could soon begin a minor-league rehab assignment, Shannon Drayer of 710 ESPN Seattle reports.

EDGE Analysis

Lewis appears unlikely to be ready to return from the 60-day injured list when the Seattle roster expands to 28 men Wednesday, but the 26-year-old outfielder may only be a week or two away from being activated. The reigning American League Rookie of the Year was batting .246 with five home runs and two stolen bases in 36 games before he was shut down in early June after undergoing surgery on his right knee.
