Alvarez (shoulder) will throw a bullpen session Saturday, Jane Lee of MLB.com reports.

EDGE Analysis

Alvarez has had a lengthy recovery process, but he seems to be making steady progress now that he's begun to throw again. The team is being careful with Alvarez and hasn't said if they'll aim to have him back this season, and rightfully so. Before getting injured in 2015, Alvarez was coming off a 2014 campaign that saw him post a 2.65 ERA and 1.24 WHIP over 30 starts.

Alvarez (shoulder) will start a throwing program this week after discovering no nerve damage to his shoulder, John Hickey of the Bay Area News Group reports.

EDGE Analysis

Alvarez has yet to pitch in a game this season, but could be ready to return to the field soon. He has experienced a few setbacks over the course of this season, most recently being shut down for three weeks back in June, and has visited Dr. James Andrews on a few occasions. Alvarez should now be able to begin taking steps forward, but the team may decide to proceed cautiously due to his past history.

Alvarez (shoulder) is without a timetable to resume throwing, the San Francisco Chronicle's Susan Slusser reports.

EDGE Analysis

He is expected to find out Saturday from the Athletics' doctors if he can begin a throwing program, according to the Bay Area News Group's John Hickey, so more information should be forthcoming. Given his low upside (career 12.6 percent K-rate) and injury history, he's only worth a stash in very deep leagues.

Alvarez (shoulder) will not throw for three weeks, Joe Stiglich of CSN California reports.

EDGE Analysis

The right-hander visited Dr. James Andrews a couple times this week following another setback with his injured shoulder last weekend. Fortunately, there was no recommendation for another surgery, but Alvarez did receive a PRP injection and will need a few weeks to let the treatment take effect. A return before the end of July would seem unlikely.

Alvarez (shoulder) was moved to the 60-day DL on Saturday, Joe Stiglich of CSN California reports.

EDGE Analysis

The move is essentially a formality, as it frees up a spot on the 40-man roster, which the A's will use to add Dillon Overton. As for Alvarez, he continues to experience soreness in his throwing shoulder and met with Dr. James Andrews twice in the last week. The move to the 60-day DL indicates that Oakland is in no hurry to rush him back into throwing after he was shut down during his last rehab start.

Alvarez (shoulder) visited Dr. James Andrews on Thursday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

The visit to the esteemed doctor was Alvarez's second in as many days, as the player and team are still trying to determine what is wrong with his shoulder. Alvarez experienced soreness following his outing with Triple-A Nashville last weekend in what was just the latest in a series setbacks. His timetable to return to the major leagues has been pushed back indefinitely.

The Athletics have decided to shut Alvarez (shoulder) down after he experienced renewed soreness following Saturday's rehab outing at Triple-A Nashville, Connor Letourneau of the San Francisco Chronicle reports.

EDGE Analysis

The 26-year-old has been on the DL all season since undergoing arthroscopic surgery on the shoulder in July 2015, but was believed to be on the cusp of returning after he made his fifth rehab start at Triple-A on Saturday. Those plans have now been tabled after this setback, and Alvarez will be forced to meet with Dr. James Andrews in the coming days for an evaluation.

Alvarez (shoulder) will pitch five or six innings in his rehab start Saturday for Triple-A Nashville and he could potentially join the A's rotation next week, MLB.com's Jane Lee reports.

EDGE Analysis

It has been a long road back from a shoulder injury for Alvarez, who gave up three runs on six hits and a walk with two strikeouts in 3.1 innings for High-A Stockton on Monday. Alvarez has not been a quality big league starter since 2014, and even then he was only missing bats at a 14.4 percent clip. If everything goes well Saturday he would be in line to jump into the A's rotation next Friday in Anaheim, replacing Zach Neal.

Alvarez (shoulder) will throw 2-to-3 innings at High-A Stockton on Monday, Jane Lee of MLB.com reports.

EDGE Analysis

Monday will mark perhaps the biggest step in the right direction that Alvarez has had during his lengthy recovery from shoulder surgery. He'll toss 2-to-3 frames in a minor league game, which officially starts the clock towards him being activated off the DL within 30 days. Alvarez will gradually have his pitch count increase in each of his rehab outings, but it's unclear if he'll immediately be able to rejoin the A's rotation upon his activation in late-June or early-July.

Alvarez (shoulder) threw 40 pitches off a mound Wednesday, Joe Stiglich of Comcast SportsNet California reports.

EDGE Analysis

This is a good sign for Alvarez, who has been battling shoulder problems since early 2015, and will now partake in another bullpen session this weekend followed by a rehab start or simulated game after that. The 26-year-old posted an impressive 2.65 ERA in 30 starts in 2014, which was his last full season, and he will look to regain that form upon his return in mid-June.
