Rocker (shoulder) will begin a rehab assignment with Double-A Frisco on Friday, Evan Grant of The Dallas Morning News reports.

EDGE Analysis

Rocker has been sidelined since late April with a right shoulder impingement but has been cleared for rehab games after getting through a live batting practice session earlier this week. He will need multiple rehab starts, assuming the Rangers intend to bring him back as a starting pitcher, but Grant raises the possibility that the club could accelerate Rocker's return by having him pitch in relief.

Rocker (shoulder) will begin a rehab assignment later this week as long as he bounces back well from a two-inning live batting practice session he threw Sunday, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

Rangers manager Bruce Bochy said Rocker's stuff looked "good" Sunday, adding that the right-hander's rehab assignment will be a lengthy one as he gets stretched back out following a three-week shutdown period. Rocker has been out for almost four weeks with a right shoulder impingement. He logged an 8.10 ERA in his first five starts this season before the injury and wouldn't seem to be guaranteed a spot in the Texas rotation once he's activated from the 15-day injured list.

Rocker (shoulder) said Thursday that he will likely throw a bullpen session next week, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

Rocker -- who was placed on the 15-day injured list last week with a right shoulder impingement -- has been throwing on flat ground and should take the next step of his progression soon. The rookie right-hander is eligible for activation late next week, but it does not sound like he will be ready to return at that time.

Rocker was placed on the 15-day injured list with a right shoulder impingement Thursday, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

Rocker was crushed in a short outing Wednesday for five earned runs across only 1.2 innings. It's unclear if he was dealing with the issue at that point, but he'll now be sidelined for at least 15 days and likely longer.

Rocker (1-3) took the loss against the Athletics on Wednesday after allowing five runs on seven hits and one walk in 1.2 innings. He struck out two.

EDGE Analysis

Fresh off establishing a career-high mark in strikeouts during his last start, Rocker was ambushed Wednesday in the shortest appearance of his career in terms of innings pitched. Although he threw 42 of his 63 pitches for strikes and managed to induce six whiffs in such an abbreviated outing, the hard-throwing right-hander struggled mightily with his command while giving up three extra-base hits. Rocker will get another chance to face these same Athletics in his next scheduled start, this time in a more favorable setting at home and away from hitter-friendly Sutter Health Park, but he's shaping up as a risky fantasy option while holding an 8.10 ERA, 1.75 WHIP and 16:5 K:BB over 20 innings (five starts) so far.

Rocker (1-2) earned the win after allowing three runs on five hits and no walks in seven innings Thursday against the Angels. He struck out eight.

EDGE Analysis

The seven frames and eight punchouts both set new career highs for the hard-throwing right-hander, who was outstanding Thursday. Jorge Soler plated a run in the opening frame, and Luis Rengifo drove in a pair in the fifth inning, but Rocker threw five spotless innings otherwise. Rocker will look to further improve on his 6.38 ERA, 1.47 WHIP and 14:4 K:BB through four starts (18.1 innings) in his next start, which is set to come against a hard-hitting Athletics lineup in Sacramento next week.

Rocker allowed one run on six hits while striking out one over five innings Sunday against the Rays. He did not factor into the decision.

EDGE Analysis

Rocker looked much better Sunday compared to his last start. The Rays scattered six singles off him, which eventually led to a run in the fourth, but Rocker showed great improvement with his command. He finished at 77 pitches and kept the Rangers in a game they went on to win in walk-off style in the ninth. Rocker will look to take the momentum of this positive start with him on the road against the Mariners next weekend.

Rocker (0-1) allowed six runs on seven hits and two walks over three innings Monday, striking out three and taking a loss against Cincinnati.

EDGE Analysis

The Reds jumped on Rocker right out of the gate with a three-run first inning, spearheaded by Matt McLain's two-run homer. Things got worse in the second with Elly De La Cruz's three-run jack. Rocker gave up just one long ball through 11.2 frames at the MLB level last year. He touched 97 mph with the fastball and forced 10 swinging strikes on 74 total pitches (45 strikes). His next start is lined up to be at home against the Rays this weekend.

Rangers president of baseball operations Chris Young said Tuesday that Rocker will be in the team's Opening Day rotation, Evan Grant of The Dallas Morning News reports.

EDGE Analysis

Injuries to Jon Gray (wrist) and Cody Bradford (elbow) seemed to make this a foregone conclusion, and now it's official. Rocker mostly struggled this spring, but he ended on a high note with eight strikeouts over 4.2 innings in his final Cactus League outing. The 25-year-old's workload in 2025 will be curtailed to some degree after he threw only 48.1 innings in 2024 following a return from Tommy John surgery.

Rocker allowed two runs on three hits and two walks while striking out eight over 4.2 innings in Thursday's spring start against the Rockies.

EDGE Analysis

Although not a perfect outing, Thursday's effort was Rocker's best in four Cactus League appearances. He had allowed 11 runs over his first 4.1 innings this spring, but this latest effort represents a second straight encouraging outing. The 25-year-old right-hander threw 76 pitches (47 strikes), as he continued to refine the mechanical issues that were on display in his first two starts. Rocker is poised to slot into the Rangers' rotation after the club lost Cody Bradford (elbow) and Jon Gray (wrist) to injuries last week.
