The Rangers recalled Rocker from Triple-A Round Rock in advance of his start Sunday against the White Sox.

EDGE Analysis

The right-hander will step into Texas' rotation Sunday with Tyler Mahle (shoulder) landing on the injured list in a corresponding transaction. Rocker has yet to find his footing through six major-league starts this season with an 8.87 ERA, 1.84 WHIP and 21:7 K:BB over 23.1 innings, but he'll have a favorable matchup Sunday to potentially get on track.

Rocker will be recalled from Triple-A Round Rock to start Sunday against the White Sox, Evan Grant of The Dallas Morning News reports.

EDGE Analysis

Tyler Mahle was the scheduled starter but is expected to be placed on the injured list due to shoulder soreness. That leaves the Rangers in need of a fifth starter, and Rocker will be tabbed for the role -- at least in the short term. Rocker was recently activated from the injured list but struggled in a start June 4 by allowing five earned runs across 3.1 innings before being sent to the minors.

Rocker is with the Rangers in Texas and could be asked to start Sunday versus the White Sox if Tyler Mahle (shoulder) is unable to pitch, Kennedi Landry of MLB.com reports.

EDGE Analysis

Though Rocker is with the team, no roster move has been made, so for now he is a contingency plan. Mahle felt some shoulder soreness during his most recent start Tuesday, but it's not yet clear if the issue is serious enough to prevent him from making his scheduled start Sunday. If Rocker is ultimately recalled to start, it would be his first appearance with the big club since he gave up five runs over 3.1 innings in a loss against Tampa Bay on June 4.

The Rangers optioned Rocker to Triple-A Round Rock on Thursday.

EDGE Analysis

Rocker was shelled for five runs in just 3.1 innings during his start Wednesday against the Rays. Poor outings have become a common theme for the 25-year-old righty this season, who now owns an 8.87 ERA and 1.84 WHIP through six MLB starts. He'll attempt to find his footing in the minor leagues; meanwhile, Chris Martin (shoulder) will return from the injured list to fill the opening in Texas' pitching staff.

Rocker (1-4) was saddled with the loss Wednesday against the Rays after giving up five runs on six hits and two walks in 3.1 innings. He struck out five.

EDGE Analysis

The hard-throwing right-hander's velocity was encouraging in his first start since April 23, as Rocker whiffed 16 and was able to touch 99 mph twice with his sinker, but his return from a right shoulder impingement was still a rocky one overall. Three of his six hits allowed went for extra bases, and Rocker notably failed to cover first base on a groundball that allowed two runs to score with two outs in the third inning. He'll bring a ghastly 8.87 ERA and 1.84 WHIP with 21 strikeouts across 23.1 innings into his next scheduled outing against the Twins, currently projected for early next week.

The Rangers activated Rocker (shoulder) from the 15-day injured list Wednesday.

EDGE Analysis

Rocker is slated to rejoin the rotation Wednesday with a start against the Rays after being sidelined since late April with a right shoulder impingement. He threw only 53 pitches and four innings in his final rehab outing, so Rocker is likely to have a limited workload versus Tampa Bay.

Rocker (shoulder) is expected to be reinstated from the 15-day injured list to start Wednesday against the Rays, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

The right-hander seemed likely require at least one additional rehab outing after throwing 53 pitches over four scoreless innings Thursday for Triple-A Round Rock, but he'll instead rejoin the Rangers with Nathan Eovaldi (triceps) placed on the injured list Sunday. Rocker figures to have some workload limitations in his first start back in the majors, but he pitched well in his two rehab outings with an 8:1 K:BB across seven shutout innings.

Rocker (shoulder) allowed one walk and struck out five over four hitless and scoreless innings for Triple-A Round Rock on Thursday.

EDGE Analysis

Rocker was untouchable, retiring the first 12 batters faced before issuing a walk to lead off the fifth inning. That ended his night. It was Rocker's second rehab appearance, which followed three scoreless innings for Double-A Midland a week prior. After the Midland game, Texas manager Bruce Bochy estimated the right-hander would need a few more starts, and that may still be the case. Rocker threw 53 pitches in the Round Rock start.

Rocker (shoulder) will transfer his rehab program to Triple-A Round Rock on Thursday, Jeff Wilson of AllDLLS.com reports.

EDGE Analysis

Rocker made his first rehab outing with Double-A Frisco this past Friday, during which he allowed two hits and no walks while striking out three across three scoreless frames. The aim for Rocker on Thursday is to reach four innings and toss 60 pitches in Triple-A, and he'll likely need at least a few more appearances before being activated from the 15-day injured list.

Rocker (shoulder) allowed two hits and no walks and struck out three over three scoreless innings Friday in a rehab start with Double-A Frisco.

EDGE Analysis

Rocker cruised Friday, making use of his full arsenal across his 34 pitches while sporting a fastball that sat around 96 to 98 miles per hour. Per MLB.com, manager Bruce Bochy said that the young right-hander will need at least a few more appearances in the minors before making his return from the 15-day injured list. Prior to being deactivated, Rocker turned in a 8.10 ERA and 1.75 WHIP over 20 innings, and he may not be a lock to reclaim a rotation spot once he returns from the IL with veteran lefty Patrick Corbin (3.59 ERA, 1.31 WHIP over eight starts) having thus far delivered decent results for the Rangers.
