Texas Rangers star shortstop Corey Seager is beyond frustrated with the state of his back, but he said that his injury will not end his season.

ARLINGTON — Corey Seager emerged from the dugout Thursday afternoon to visit his brother Kyle, the former Texas Rangers killer. Don’t worry: Kyle Seager remains retired and was not in the Angels’ lineup.

Corey Seager was not in the Rangers’ lineup, still stuck on the injured list because of a recurring back injury that flared up again last week in Cleveland. Updates from Skip Schumaker haven’t contained much information other than Seager continues to rest and get treatment, though the manager did say he had not heard that a stress reaction is causing Seager’s woes.

Seager shed more light on his status after visiting his brother. After a series of MRI exams and visits with various specialists, Seager said that his injury is not a season-ender and that he could return before the end of the month.

He was recently advised by Dallas-based specialist Dr. Drew Dossett not to resume baseball activities until he has five to seven consecutive good back days, meaning he won’t be back before the All-Star break. Seager, who is eligible to come off the IL on Saturday, said he has had two straight good back days.

“It’s really frustrating,” he said.

The good news, he said, is that the back has improved. The bad news is he can do only core work in an attempt to strengthen his back. The Rangers are also planning to take things slowly with Seager, who was initially diagnosed with a back issue in mid-May.

He missed 19 games before returning June 4 but lasted just six games before suffering a concussion that cost him 12 games. Seager played only three games before the back started barking again.

The Rangers are 15-22 with Seager on the IL. He’s played only 50 games this season, and the Rangers are 26-23 when he plays. They need him, even though he’s batting only .182 with 10 home runs.

A healthy and productive Seager would give the Rangers a boost when they might be searching for offensive help at the Aug. 3 trade deadline. There has also been some scuttlebutt that the Rangers would have interest in trading Seager, who is owed $155 million over the next five seasons.

He will gain 10-and-5 rights (10 years’ service time, five with the same team) after the season and can veto any trade. He currently has limited no-trade protection to eight teams.

“My wish is to have our guys of the IL,” Schumaker said.

One returned Thursday. Wyatt Langford was reinstated after seeing remarkable improvement in his left hamstring over the past five days, and a new round of MRI imaging confirmed that the strain has healed.

He was at designated hitter in the finale against the Rangers, who started left-hander Reid Detmers. That sent Joc Pederson, who doesn’t face lefties, to the Rangers’ bench and gave the Rangers a chance to ease Langford back from the IL.

The Rangers initially believed that Langford wouldn’t return until after the All-Star break. Schumaker said that the Rangers’ 46-46 record and need for a surge before the trade deadline were not behind the quicker-than-expected return.

“We would never put his health in jeopardy based on where we’re at,” Schumaker said.

Left-hander Jordan Montgomery (elbow) could be two weeks away from returning. He is scheduled to make his fourth rehab start Sunday for Triple A Round Rock, and would need at least one more to get stretched out enough to give the Rangers some length.

Fellow lefty Cody Bradford (elbow) will start a rehab assignment Sunday, tossing one inning for Double A Frisco.
