Riley O’Brien’s Breakout Season Culminates in All-Star Selection
At 31, the Cardinals closer is making his first All-Star appearance after a remarkable first full MLB season, overcoming early-season struggles and a missed WBC opportunity.


Rising to prominence in his first full Major League Baseball season, St. Louis Cardinals closer Riley O’Brien has earned a spot on the National League All-Star roster. At 31 years old, O’Brien’s journey to this accolade is marked by a significant breakout performance after limited big league experience prior to 2026.
A Family Affair in Philadelphia
The All-Star Game marks a significant personal milestone for O’Brien, who will be joined in Philadelphia by his parents, wife, and brother. The family is reportedly preparing for the festivities, including a red carpet appearance. “They’re getting outfits ready for the red carpet and stuff,” O’Brien shared with reporters. “They’re looking forward to it, for sure.” O’Brien himself plans to rely on his wife and mother for his red carpet attire, noting the need for tailoring due to his slender frame.
Overcoming Adversity and Expectations
O’Brien’s path to the All-Star team wasn’t without its challenges. He began the season by declining to pitch in the World Baseball Classic for Team Korea due to a calf strain, a disappointment that preceded his first full big league season. Despite the initial setback, O’Brien has excelled in his role as the Cardinals’ closer. He currently ranks among the league leaders in saves, trailing only Mason Miller and Jhoan Duran.
“Maybe early on in the year when things were going really well,” O’Brien admitted when asked if an All-Star nod was on his radar. His season started strong, with 13 consecutive appearances without allowing an earned run. However, he experienced a challenging period where runs became more frequent. “It felt like I couldn’t go out there without giving up a run,” O’Brien said. “But yeah, it feels good to come back — I knew that wasn’t going to last forever. I felt like what I did at the beginning of the year was more the version of myself and the rough patch was just something I was going to get through rather than the other way around.”
Managerial Perspective on Growth
Cardinals manager Oliver Marmol highlighted O’Brien’s development in high-pressure situations as a key aspect of his success. “I don’t think you really know who you are until you’ve encountered that,” Marmol commented on O’Brien’s experience in the closer role. “It’s easy to be consistent and have a certain personality and come in a certain way while things are going good. You really find out about yourself and about others when that’s not the case.” This ability to navigate adversity is crucial for a closer, a role O’Brien has rapidly assimilated into.
A Non-Traditional Trajectory
O’Brien’s ascent to the closer role has been notably swift. Acquired by the Cardinals from the Mariners in November 2023 for cash considerations, he had only appeared in two career MLB games prior to his arrival. This rapid integration into the ninth inning highlights his adaptability and mental fortitude. “The more I kept throwing in the ninth inning, late innings in games, I just felt more comfortable,” O’Brien stated. “Just settling into the role, knowing that the ninth inning is mine — just all the prep and the mental preparation, too — I think it’s just being comfortable in that role now.”
Ryne Stanek, a fellow Cardinals reliever, praised O’Brien’s growth, noting that his development off the field has been as significant as his on-field performance. “On the field stuff is pretty self-explanatory, but how you get there is, usually, what separates a lot of people,” Stanek said. “I think he’s got a pretty good handle on what he needs to do.” O’Brien’s story is a testament to perseverance and seizing an opportunity, culminating in a well-deserved All-Star selection.
