Matt Brash has started a throwing program.

EDGE Analysis

Brash continues to slowly work his way back from a lat injury. He is targeting a return in mid-to-late August.

General manager Justin Hollander said Tuesday that Brash was diagnosed with a Grade 1 strain in his right lat, Shannon Drayer of SeattleSports.com reports.

EDGE Analysis

Brash has suffered multiple right lat strains this season, though Hollander noted that his latest injury is in a different spot than the one that kept him out for three weeks in May. He also said that the 28-year-old righty is facing a longer stint on the IL this time around and is likely to return sometime around late July or early August. Until then, Jose Ferrer, Gabe Speier and Eduard Bazardo figure to work more often in high-leverage situations.

Brash has returned to Seattle to have his right lat strain evaluated further, Daniel Kramer of MLB.com reports.

EDGE Analysis

Brash missed most of May with a strained lat and then went back on the 15-day injured list Wednesday after aggravating the injury. More should be known about a timetable once he's looked at by doctors in Seattle, but manager Dan Wilson acknowledged Thursday that there is "going to be a little bit more time down" for Brash during this second IL stint.

The Mariners placed Brash on the 15-day injured list Wednesday due to a right lat strain.

EDGE Analysis

Seattle recalled right-hander Domingo Gonzalez from Triple-A Tacoma to take Brash's spot in the bullpen. Brash has served as one of the top setup arms in front of closer Andres Munoz this season, notching three wins and six holds while accruing a 0.54 ERA, 0.84 WHIP and 15:6 K:BB across 16.2 innings over his 20 appearances.

The Mariners reinstated Brash (lat) from the 15-day injured list Wednesday.

EDGE Analysis

Seattle optioned left-hander Robinson Ortiz to Triple-A Tacoma to make room on the active roster and in the bullpen for Brash, who had been shelved since May 1 due to right lat inflammation. He was cleared to rejoin the Mariners after a pair of rehab appearances with Tacoma, during which he posted a 4:2 K:BB while not allowing a hit over 1.2 innings.

Brash (lat) will begin a rehab assignment with Triple-A Tacoma on Thursday, Daniel Kramer of MLB.com reports.

EDGE Analysis

Brash resumed throwing off the mound earlier this week and is now ready to test things out in a game setting. The setup reliever has been out for all of May with right lat inflammation but appears close to a return if he can avoid a setback.

Brash (lat) will throw a bullpen session Monday, Shannon Drayer of SeattleSports.com reports.

EDGE Analysis

It will be the first time he's thrown from the bump since he landed on the 15-day injured list at the beginning of May with right lat inflammation. Brash is eligible for activation from the IL on Friday and has a chance to return on that date, though the Mariners might want to have him make a rehab appearance or two first.

Brash (lat) began playing catch Tuesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

It's the first time Brash has done any kind of throwing since he landed on the injured list Friday with right lat inflammation. A clearer timeline for his return may begin to take shape once he progresses to throwing off a mound.

The Mariners placed Brash on the 15-day injured list Friday, retroactive to Thursday, due to right lat inflammation.

EDGE Analysis

Brash sustained the injury during Wednesday's outing against the Twins, when he tweaked his lat while tossing two pitches in the eighth inning. While the MRI didn't reveal any structural damage, the injury is significant enough for him to warrant a stint on the IL. A minimum stay on the IL would mean a mid-May return for Brash, but some lat injuries take longer to heal from, so it wouldn't be surprising to see the right-hander shelved until the end of the month or early June. Left-hander Josh Simpson was recalled from Triple-A Tacoma in a corresponding move.

Mariners manager Justin Hollander told reporters Friday that an MRI on Brash revealed "trace inflammation" in his right lat and no signs of structural damage, Daniel Kramer of MLB.com reports.

EDGE Analysis

Brash sustained the injury during Wednesday's game against the Twins after tossing just two pitches in the eighth inning. The fact there was no structural damage is good news for the 27-year-old right-hander, but the inflammation in his lat could result in a stint on the 15-day IL. It would be a big blow to the Mariners' bullpen, as Brash has yet to give up an earned run across 11.1 innings this season, allowing just three hits and two walks while striking out eight and accumulating four holds.
