Lewis (concussion) is scheduled to shift his rehab assignment to Triple-A Tacoma this week and is expected to make regular starts in the outfield, Daniel Kramer of MLB.com reports.

EDGE Analysis

According to Kramer, the Mariners have already ruled out activating Lewis from the 7-day injured list prior to the All-Star break, but the 26-year-old is trending toward being ready to go when the big club opens its second-half schedule July 22. Through the first five games of his rehab assignment -- which has included one game with Tacoma and four with High-A Everett -- Lewis has served exclusively as a designated hitter while going 4-for-10 with three home runs and two walks.

General manager Jerry Dipoto said Thursday that he hopes Lewis (concussion) will rejoin the major-league club before the end of July, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Although Lewis recently began a rehab assignment, Dipoto said that the 26-year-old's return from the 7-day injured list isn't yet imminent. Lewis has gone 0-for-3 with an RBI, a walk and two strikeouts while serving as a designated hitter over his first two rehab games with High-A Everett, but the Mariners want to see him get more work in the outfield before he's cleared to rejoin the major-league club.

Lewis (concussion) has joined Triple-A Tacoma and is expected to begin a rehab assignment as soon as Sunday, Daniel Kramer of MLB.com reports.

EDGE Analysis

Lewis has resided on the 7-day injured list since June 1, so he'll need at least a handful of games in the minors to get his timing back at the plate following the month-plus absence. Manager Scott Servais said Sunday that Lewis will see a healthy dose of playing time in the outfield while on assignment, so the Mariners could view him as a potential replacement in right field for the injured Taylor Trammell (hamstring), who is without a clear timeline to return from the IL. Before sustaining the concussion, Lewis had made all four of his starts with Seattle this season as a designated hitter.

Lewis (concussion) took batting practice again Tuesday and added sprint drills out of the batter's box following his final swing of each round, Daniel Kramer of MLB.com reports.

EDGE Analysis

Lewis was also wearing elastic stretch bands on his right leg, which were designed to help him with his running form and ensure his surgically repaired knee remained elevated upon his initial burst. The slugging outfielder is unsure of a return date, and he noted he remained bedridden for the first week following his concussion due to his sensitivity to bright lights and loud sounds. However, the fact he's now consistently elevating his heart rate during baseball activities could be the final step before he's cleared for a minor-league rehab assignment.

Lewis (concussion) took batting practice ahead of Monday's game against the Orioles, Shannon Drayer of 710 ESPN Seattle reports.

EDGE Analysis

Lewis has been ramping up his baseball activities since mid-June, and his participation in batting practice Monday is certainly an encouraging sign. It's not yet clear when the Mariners expect the 26-year-old to return or whether he'll require a rehab assignment prior to being activated.

Lewis (concussion) has ramped up baseball activities in recent days but remains without a firm return timetable, the Associated Press reports.

EDGE Analysis

Lewis' recovery from a concussion has been rather drawn out, as the slugging outfielder has been on the injured list since June 1. The fact Lewis remains without a timetable for his return underscores the unpredictable nature of head injuries, but he is reportedly showing gradual improvement.

Manager Scott Servais said Friday that Lewis (concussion) hasn't yet resumed baseball activities, Daniel Kramer of MLB.com reports.

EDGE Analysis

Lewis has been working on his conditioning by riding a stationary bike recently, but he hasn't yet been cleared to ramp up his workload. Since Lewis has been sidelined for nearly two weeks due to his concussion, he'll require a rehab assignment before he's ultimately cleared to rejoin the Mariners.

Lewis (concussion) has begun working on his conditioning by ramping up his heart rate on a stationary bike, but he remains without a firm return date, Daniel Kramer of MLB.com reports.

EDGE Analysis

The uptick in activity is encouraging considering he's been experiencing prolonged concussion symptoms. However, Lewis has yet to resume any baseball activities, a step he'll naturally have to complete before activation is considered. Lewis is scheduled to be reassessed when the Mariners return home for a weekend series against the Red Sox.

Manager Scott Servais said Saturday that Lewis is still dealing with concussion effects, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Lewis was placed on the 7-day injured list Wednesday, and he hasn't yet been able to do any strenuous activity as the Mariners follow concussion protocols. It's not yet clear when the 26-year-old will be able to return to game action.

The Mariners placed Lewis (concussion) on the 7-day injured list Wednesday.

EDGE Analysis

Reports surfaced Tuesday that Lewis was out of the lineup for the second game in a row due to concussion-like symptoms, so his placement on the 7-day IL doesn't come as too much of a surprise. He'll be eligible to return from the IL on Sunday, but Lewis will first need to pass all neurological testing before he's cleared to resume playing. In a corresponding move, the Mariners activated Abraham Toro (shoulder) from the 10-day IL on Wednesday, and he could end up serving as the main replacement for Lewis in Seattle's everyday lineup.
