Seattle Mariners outfielder Greg Halman was stabbed to death in Rotterdam on Monday and his brother has been arrested in connection with the incident, police said.
Halman, 24, was signed as a free agent by Seattle in 2004 and made his major league debut in 2010.
Police were called to a home in the Dutch port city early Monday and found Halman bleeding from a stab wound. The officers were unable to resuscitate the outfielder.
"A 24-year-old died this morning in a stabbing and we have arrested the 22-year-old brother of the victim," a Rotterdam police spokesman told Reuters. Officials declined to give the suspect's name, in line with Dutch privacy rules.
Police spokesman Patricia Wessels told the Associated Press: "He is under arrest and right now he is being questioned. It will take some time to figure out what exactly happened."
However, Halman's 22-year-old brother Jason reportedly played at the 2004 World Baseball Championship in Taiwan. According to baseball-reference.com, their father Eddy played professionally in Holland.
NOS-TV said Halman's family had confirmed his death.
