Source-derived summary

Gregory Anthony Halman (August 26, 1987 – November 21, 2011) was a Dutch professional baseball outfielder. He played with the Seattle Mariners of Major League Baseball (MLB) in 2010 and 2011. He played for the Netherlands national team in the 2009 World Baseball Classic and other international tournaments. He died in Rotterdam in November 2011 after being stabbed at the home of his younger brother, Jason Halman, who was arrested in connection with the stabbing then acquitted on the grounds of temporary insanity.

Playing career

The Netherlands

Halman, like his father Eddy Halman and younger brother Jason, played professional baseball in the Netherlands and on the Netherlands national team. Halman debuted when he was 16 years old with the Dutch Honkbal Hoofdklasse team Kinheim in Haarlem in 2003. That season, he led the league with six triples. The next year, Halman was one of the best players in the country, batting .358 with a league-leading 4 home runs, 4 triples, and 41 runs batted in (RBIs). He hit for the cycle in a May game against Sparta-Feyenoord. He won the league's most valuable player award and was named the most promising young Dutch player.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1987, 2011, 2010, 2009—that can be checked directly. The linked authority record independently contributes the date 1987-08-26. For this dossier, Greg, Halman and Dutch is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “dutch professional baseball player (1987-2011)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated May 26, 2026. The linked authority identifier is Q3116243. VIAF identifies the subject as 313043007. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1987, 2011, 2010 and 2009.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
