Brian Matusz, a former first-round pick in the MLB draft who spent eight years with the Baltimore Orioles, died Tuesday at the age of 37.
As of Wednesday, no cause of death has been reported.
The lefty, who began his career as a starting pitcher before becoming a specialist out of the bullpen, made 280 career appearances – all but one for the Orioles.
The team made a heartfelt tribute late Tuesday on social media to their longtime clubhouse stalwart.
“Our hearts are heavy tonight as we mourn the passing of former Oriole Brian Matusz,” the team wrote on X.
“A staple in our clubhouse from 2009-2016, Brian was beloved throughout Birdland, and his passion for baseball and our community was unmatched. He dedicated his time to connecting with any fan he could, was a cherished teammate, and always had a smile on his face.
“Brian’s family and loved ones are in our thoughts and prayers at this difficult time.”
Adam Jones, an Orioles great and longtime teammate of Matusz, also posted a tribute on social media.
“Wow. Just wow,” Jones posted on X. “RIP to a good friend and teammate. We had some amazing times on and off the field. Rest easy my friend. Wow.”
Matusz, who was born in Grand Junction, Col., originally was drafted out of high school in the fourth round of the 2005 draft by the Angels but opted to attend the University of San Diego. He boosted his stock there, becoming the fourth overall pick of the 2008 draft by the Orioles.
After less than a full season in the minors, Matusz made his major-league debut on Aug. 4, 2009.
He made a career-high 32 starts in 2010, finishing fifth in the American League Rookie of the Year voting.
After an ineffective 2011 season and poor start to 2012, he was shifted to the bullpen, where he regained his footing.
In each season from 2013 to 2015, he appeared in at least 58 games and lowered his ERA each year until hitting a career-best 2.94 in 2015.
After making seven appearances for the O’s in 2016, he was traded to the Atlanta Braves, who released him. Matusz later signed with the Chicago Cubs, making just one MLB appearance – which turned out to be the last of his career — for the eventual World Series champions.
More recently, Matusz served as a bullpen coach for New Zealand at the 2022 World Baseball Classic.
