Matusz showed promise as a starter and later distinguished himself as a reliever, pitching in 279 games total for the Orioles between 2009 and 2016.
The 37-year-old was found dead in his Arizona home with a white substance in his mouth alongside a lighter, straw and aluminum foil, the report stated.
Former Baltimore Orioles pitcher Brian Matusz’s cause of death was likely a drug overdose, according to a police report cited by The Baltimore Banner on Monday.
He also pitched in the postseason for the Orioles, appearing in all five games against the New York Yankees in the ALDS in 2012. He returned to the playoffs with the O’s in 2014.
The team announced last week that Matusz had died, writing on X, “Our hearts our heavy.”
