Sborz (shoulder) began a rehab assignment with Double-A Frisco on Saturday.

EDGE Analysis

Sborz has been on the injured list since Aug. 11 due to right shoulder fatigue. It's unclear how many appearances the Rangers want the 30-year-old to make before they activate him off the IL, though a return before the end of the month hasn't yet been ruled out.

The Rangers placed Sborz on the 15-day injured list Sunday due to right shoulder fatigue.

EDGE Analysis

Sborz's placement on IL is retroactive to Thursday, so he'll be eligible for activation as soon as Aug. 23. The right-hander has been a key setup man for the Rangers when available this season but had struggled of late, giving up a run in three of his last five appearances. Texas called up right-hander Matt Festa from Triple-A Round Rock to take Sborz's spot in the bullpen.

Sborz allowed one hit and struck out three over two scoreless innings in Sunday's 3-2 win over the Orioles.

EDGE Analysis

Sborz made his fourth appearance since coming back from a shoulder injury. He hasn't issued a walk in six innings since coming off the IL and has hurled five consecutive scoreless frames. When healthy, Sborz is used as a high-leverage arm in the bullpen. He has a 2.38 ERA with 11 strikeouts and three walks over 11.1 innings this season.

The Rangers activated Sborz (shoulder) from the 15-day injured list Friday, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

Sborz missed nearly two months of action with right shoulder tightness but is ready to go after allowing just one run with a 9:2 K:BB over his last 5.1 rehab innings. A high-leverage bullpen role awaits Sborz, although he could be eased back into such situations.

Sborz (shoulder) allowed two runs on two hits and one walk while striking out one over two-thirds of an inning for Triple-A Round Rock on Sunday.

EDGE Analysis

Sborz started a rehab assignment Sunday and threw 20 pitches (10 strikes), with his fastball topping out at 95.7 mph. Per Kennedi Landry of MLB.com, Sborz had been scheduled to throw an inning. Texas manager Bruce Bochy didn't give a specific number of outings or innings for the reliever, who's been out since May 8 with right shoulder tightness.

Sborz (shoulder) will begin a rehab assignment with Triple-A Round Rock on Sunday, Evan Grant of The Dallas Morning News reports.

EDGE Analysis

A right rotator cuff strain put Sborz on the injured list May 9, but he made it through live BP earlier this week and has since gained clearance to start up a rehab assignment. Sborz compiled a win and three holds in seven appearances before going down. He should slot back into a fairly prominent role in the Rangers' bullpen when ready, though not quite at the back end.

Sborz (shoulder) headed to Triple-A Round Rock on Wednesday to begin throwing live batting practice, Kennedi Landry of MLB.com reports.

EDGE Analysis

If all goes well in live BP sessions, Sborz will embark on a rehab assignment shortly after. This is Sborz's second stint on the injured list this season due to a right rotator cuff strain.

The Rangers placed Sborz on the 15-day injured list Thursday with a right rotator cuff strain.

EDGE Analysis

This marks the second time already this season that Sborz has had to spend time on the injured list due to a strained rotator cuff. His first IL stint lasted roughly two-and-a-half weeks, though it's possible the Rangers bring him back slower this time around to minimize the risk of re-injury. A corresponding move will be made ahead of Friday's game against the Rockies.

Sborz was removed from Wednesday's game against the Athletics with an apparent injury, Kennedi Landry of MLB.com reports.

EDGE Analysis

Sborz only threw eight pitches before having to leave Wednesday's game -- seven of which missed the strike zone. It's not immediately apparent what is bothering the 30-year-old right-hander, but the Rangers should offer more details following the game.

Sborz threw a scoreless ninth inning in Thursday's 4-3 loss to Seattle.

EDGE Analysis

Sborz, who was activated off the injured list Thursday, retired the side in order, needing just nine pitches. He was placed on the IL due to a shoulder injury April 7 after just three appearances. The back end of the bullpen has changed since then -- Kirby Yates replaced Jose Leclerc as the closer -- but Sborz should remain part of the setup group.
