Seattle Mariners outfielder, Greg Halman, was stabbed to death at Rotterdam in the Netherlands Monday. Halman's brother has been arrested in connection with the murder, police said.

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.

As Greg has only one brother, it is very clear that the arrested man is his brother Jason Halman.

Greg, who helped the Netherlands win European Baseball championship in 2007, joined the Major League team in 2010 and played 35 games for the Mariners. He hit .230 in 87 at-bats with two home runs and six RBI. He was the only Netherlands-born MLB player.

He was on the Mariners' 40-man roster and regarded as a challenger for a position in left field or as a backup to center fielder Franklin Gutierrez.

Greg's 22-year-old brother Jason also played baseball for the Netherlands, and was also a part of the national team for the 2004 World Baseball Championship played in Taiwan. Their father, Eddy, also played professionally in Holland.

With the news of Greg's murder on MLB's official Web site, condolences started pouring in from his fans.

Very sad to hear about this, he was a classmate for 2 years and a really stand-up guy. Can't understand how or why this would happen, he was so close to Jason. R.I.P. Gregg, a fan named Enswan posted.

What a shame; such a senseless tragedy. Just goes to show how incredibly insignificant sports really is, in the grand scheme of things--like life. Much sympathy to his immediate family and also his extended family, the Mariners, and to all who knew, cared and loved the young man, another fan posted.

Greg graduated from Mendel College in North Holland in 2004.
