Former Baltimore Orioles pitcher Brian Matusz, a first-round pick in 2008 and a beloved member of the team for eight seasons, was found dead Monday after police in Phoenix responded to a call about a body at a home, law enforcement officials said Wednesday.

The incident is being handled as a death investigation and Matusz’s remains were recovered by the Maricopa County Office of the Medical Examiner, police said.

The manner and cause of death are not known, and police have not said whether they suspect foul play was involved.

The medical examiner’s office cannot comment on Matusz’s death because “it is [an] open and pending investigation,” a representative said.

Matusz was 37.

In a statement released Tuesday night, the Orioles said: “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.”

Born in Grand Junction, Colorado, Matusz went to high school in Phoenix, where he received first-team all-state honors during his junior season and was named Arizona player of the year as a senior. He went to the University of San Diego and was drafted by the Orioles fourth overall in 2008, making his major league debut a year later.

He had his best season as a starter in 2010, earning a fifth-place finish in American League Rookie of the Year voting after pitching to a 4.30 ERA in 32 starts.

Injuries limited him in 2011, and he was moved to the bullpen beginning in 2012. There, he had some of his most memorable appearances for the Orioles, including pitching in all five playoff games during their 2012 run. He played a large role in the team’s success in 2014 as well, recording a 3.48 ERA in 63 games as the Orioles won the American League East.

“He was a big part of our success,” former Orioles manager Buck Showalter, who managed Matusz for seven seasons, said Wednesday. “We were very picky about getting the right attitude, makeup, guys who would fit into who we wanted to be. Brian was one of them.”

Matusz remained with the team until midway through the 2016 season, when the Orioles traded him to the Braves, who designated him for assignment before he appeared in a game. Matusz then signed a minor league deal with the Cubs, making his final major league appearance later that season for Chicago.

“I’m going to dwell on the great memories of Brian and that smile and how much he enjoyed the success we had there,” Showalter said. “He loved to compete; he had a talented hand. It’s just a lesson to all of us how fleeting things can be.”
