Blake Treinen, the Los Angeles Dodgers pitcher, hurt his right shoulder while warming up on September 26, 2026. This article explains what happened, what the team has said, what is still unknown, and who Treinen is. It matters right now because the Dodgers are heading into October without one of their most experienced arms.
Background: Who Is Blake Treinen and Why Are People Searching for Him?
Blake Treinen is a relief pitcher. That means he usually comes into a game after the starting pitcher leaves, often to protect a lead in the late innings. He is known for a heavy, sinking fastball that hitters tend to pound into the ground.
He has won three World Series titles, in 2020, 2024 and 2025, and made the All-Star team in 2018. He is also the longest-tenured pitcher on the Dodgers, having joined in 2020. People are searching his name because a bullpen injury this close to the playoffs is big news, and because fans remember how many times his body has let him down.
Latest Update
As of September 28, 2026, here is what is currently known.
Treinen was warming up in the bullpen during the seventh inning when his right shoulder went wrong. He stopped throwing and walked off with a trainer, and Brock Stewart pitched in his place. Manager Dave Roberts told reporters afterward that Treinen’s season is over. Roberts also said the team did not know if it was a “complete blowout,” which is a plain way of saying the damage had not been measured yet.
Treinen is going to be placed on the injured list. He had also just come back. He had been out since June 20 with right elbow inflammation, missing 62 games, and was reactivated on September 2. In seven games after returning, he gave up three runs in 6 2/3 innings, which works out to a 4.05 ERA. He was not being used in the most pressure-filled moments.
What does this do to the Dodgers? Reports say the team’s best relievers are mostly left-handed, led by Tanner Scott, Jack Dreyer and Alex Vesia. Brock Stewart and Evan Phillips are the most trusted right-handers. Edgardo Henriquez and Will Klein could return for the playoffs, and one report expects Edwin Díaz to be used sooner than planned. In plain terms, Treinen was a depth arm this fall, so the team can cover his innings, but it has fewer proven right-handers to choose from.
The timing is also a contract story. Most sources, including Baseball-Reference and MLB Trade Rumors, say his two-year, $22 million deal ends after 2026, which would make him a free agent this winter. One fantasy site, RotoWire, says he has one year left. Because the majority of sources and the deal’s stated length agree on the free-agent version, that is what this article uses, but the disagreement is worth knowing about.

Full Profile
Family and Early Life
Treinen grew up in a small Kansas town where his relatives lived close by. As a freshman he played baseball for his high school, then quit during his sophomore year after he developed prediabetes, a condition where blood sugar runs high but has not yet reached diabetes. He returned for his junior year and slowly worked his way into a real pitching prospect.
Career Path
Oakland drafted him in the seventh round in 2011. He made his major league debut with the Washington Nationals on April 12, 2014. He moved to the Oakland Athletics in July 2017 and had his best year in 2018, when he was an All-Star.
His road to the majors was slow. The Florida Marlins picked him in the 23rd round in 2010, but he did not sign and went back for his senior year. A year later Oakland took him higher, in the seventh round, and gave him a signing bonus of about $52,500, according to The Baseball Cube.
The Dodgers signed him to a one-year deal in December 2019, and he has stayed since. Through September 23, 2026, Wikipedia lists his career record as 49-42 with a 2.94 ERA, 627 strikeouts and 83 saves. Those numbers may change slightly, since the season is not over.
His last two seasons were rough on the stat sheet. In 2025 he missed over three months and posted a 5.40 ERA in 26 2/3 innings, with more walks than usual and fewer ground balls than in his prime. That is a big reason some fans see this as a possible turning point, though only Treinen and the team can say what happens next.
Age
Treinen was born on June 30, 1988, so he is 38 years old as of September 28, 2026. At that age, coming back from repeated arm problems is harder, which is why the current injury draws so much attention.
Religion
Treinen is a Christian and talks about it openly. He has said he was raised in a Christian home and that his own faith grew stronger later, including through a college program called Athletes in Action. He credited Jesus Christ on camera after the 2024 World Series win.
Treinen has also spoken publicly about his convictions in other settings. In 2023 he criticized the Dodgers’ plan to honor a group at Pride Night, and he said his beliefs come before baseball. Those views are his own and have drawn both praise and criticism from fans.
Spouse/Partner
Treinen is married to Kati. According to MLB.com, she played college basketball at Walla Walla and Boise State and later became an assistant women’s basketball coach at Walla Walla. A Spokane newspaper reported in 2020 that the family lived in Walla Walla, Washington.
MLB.com says the couple has four children. Their names are not confirmed by an official source, so they are not listed here.
Net Worth
No credible source has confirmed his net worth. What can be checked is his pay: Baseball-Reference lists his 2026 salary at $13.5 million, under a two-year, $22 million contract. Websites that give a single net worth number do not show how they got it, so treat it as unconfirmed.
Parents
One low-quality website names his parents as Tim and Gete Treinen. No major outlet backs that up, so the names are unconfirmed.
Height
Baseball-Reference lists him at 6 feet 5 inches (196 cm) and 225 pounds (102 kg).
Education
He graduated from Osage City High School in 2006. In college, he played junior varsity at Baker University in 2007, then enrolled at the University of Arkansas, where he could not play baseball. He transferred to South Dakota State University, sat out 2009 under transfer rules, then pitched there in 2010 and 2011. The Dodgers say he graduated from South Dakota State.
Hometown/State of Origin
He was born in Wichita, Kansas, and raised in Osage City, Kansas. His state of origin is Kansas.
Official Social Media
Baseball-Reference lists his Instagram handle as blaketreinen49: instagram.com/blaketreinen49. Check for the verified badge before sharing, because I could not confirm it directly.

Is Blake Treinen out for the playoffs?
Yes. Manager Dave Roberts said his season is over, which rules him out of the postseason. The Dodgers can still add other relievers.

Is this the same shoulder he had surgery on before?
Yes, it is his right shoulder, which had labrum and rotator cuff surgery in November 2022. Whether the two problems are connected has not been confirmed, and one report calls it uncertain.
How old is Blake Treinen?
He is 38. He was born on June 30, 1988.
Who is Blake Treinen’s wife?
His wife is Kati, a former college basketball player who became an assistant coach at Walla Walla. Reports say they have four children, though the children’s names are unconfirmed.
Will Blake Treinen retire or leave the Dodgers?
That is unknown. Most sources say his contract ends after 2026, so he is expected to become a free agent, but he has not announced any decision about retiring or signing elsewhere.
Wrap-Up
The facts are short. Treinen felt his right shoulder give out while warming up on September 26, 2026, the Dodgers say his season is over, and doctors have yet to share what the scans show. Everything beyond that, from surgery to his future, is guesswork until someone with real information says otherwise.
The bigger picture is a career built on coming back. He lost most of one year and all of another to shoulder surgery, then returned to help win titles in 2024 and 2025. This year he missed more than two months with his elbow and got only seven games back before the shoulder failed.
For the Dodgers, the loss is manageable because Treinen was not a top late-inning option this fall, and other pitchers will take those spots. For Treinen, the question is larger: another repair, a long rehab, and a contract decision, all at 38. Check back for updates once the imaging results are officially released.
