Alvarez will make his next rehab start Monday with Triple-A Nashville, Jane Lee of MLB.com reports.

EDGE Analysis

Alvarez fired three innings in his first rehab appearance with High-A Stockton, giving up a run on three hits while striking out one batter. He's making steady progress through his rehab program, and it appears he's staying on schedule for a return in late-May or early-June.

EDGE Analysis

This marks a big step toward returning to the big leagues after Alvarez suffered a partial UCL tear last May, but the team will still likely take it slowly with the 26-year-old. They're currently targeting a late-May or early-June return, but the timetable could change depending on how Alvarez feels following his first game action.

The A's are targeting a late may or early June return date for Alvarez (shoulder), John Hickey of the Bay Area News Group reports.

EDGE Analysis

Alvarez is slated to throw one more bullpen session before setting out on a rehab assignment, according to Jane Lee of MLB.com. Given the nature of his injury and the amount of down time following his shoulder surgery, the A's will be patient with him and give him multiple starts at the minor league level before plugging him into the big league rotation.

Alvarez (shoulder) will throw a simulated game at the O.co Coliseum on Friday, Jane Lee of MLB.com reports.

EDGE Analysis

After facing live hitters on Tuesday, Alvarez continues his road to recovery with this simulated game. If all goes well, he'll remain on track for a mid-May return. After an All-Star season in 2014, Alvarez struggled to stay healthy with a shoulder injury last year, but looks increasingly closer to returning.

Alvarez (shoulder) has returned to the Athletics after throwing 30 pitches against minor league batters with High-A Stockton, John Hickey of the Bay Area News Group reports.

EDGE Analysis

This is a good sign for the right-hander, especially considering he was able to use all of his pitches in the outing. Alvarez still has a way to go in his recovery, but it's promising that a return in mid-May is still realistic.

Alvarez (shoulder) threw 25 pitches in a live batting practice session Wednesday, Jane Lee of MLB.com reports.

EDGE Analysis

Alvarez had been limited to just throwing bullpen sessions of late, but he moved up to facing live batters Wednesday for the first time since undergoing shoulder surgery. He told reporters following Wednesday's session that his shoulder felt good and that May is still in the realm of possibility for his return date. Alvarez's next batting practice session is scheduled for Sunday.

Alvarez (shoulder) was placed on the 15-day disabled list on Saturday.

EDGE Analysis

Alvarez has been long expected to start the season on the disabled list due to his lengthy recovery from shoulder surgery, and the A's finalized the move Saturday with Opening Day looming. However, Alvarez has been upping his pitch counts during recent bullpen sessions and is scheduled to face live hitters Wednesday. If he continues to recover at this pace, he could be back on the mound some time in mid-May.

Alvarez (shoulder) will face hitters next Wednesday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Alvarez has been ramping up his rehab in recent days, and it appears that he's progressed enough to face live hitters. He's still a ways away from game situations, but the progress he's made still points toward a mid-May return.

Alvarez (shoulder) will throw a 40-pitch bullpen session Saturday, John Hickey of the San Jose Mercury News reports.

EDGE Analysis

For the first time this spring, Alvarez will mix breaking pitches into his arsenal when he's on the bump for a bullpen session. He's still a ways away from being ready for game action, but he has increased his pitch count during his bullpens and is gradually working mixing in all of his pitches. If Alvarez's bullpen Saturday goes without a hitch, he should remain on track for a return some time in May.

Alvarez threw a 30-pitch bullpen Tuesday and used his change-up for the first time this spring, reports Jane Lee of MLB.com.

EDGE Analysis

Alvarez continues to progress in his return from right shoulder surgery and experienced no issues in this bullpen session Tuesday. He has felt good in every step of his work so far this spring and has a chance to return to the A's by mid-May. Upon his return, it is assumed that he will join the rotation, either filling in for an injured starter or replacing a struggling one.
