Houston goalkeeper Pat Onstad has retired to take an assistant coaching job at D.C United.
The 42-year-old Onstad, the oldest player in Major League Soccer this past season, helped lead the Dynamo to consecutive MLS Cup championships during his five years in Houston.
The Vancouver native started his MLS career in 2003 with San Jose and helped San Jose to its second MLS Cup championship. The club moved to Houston before the 2006 season.
The Dynamo also led the league with the fewest goals allowed in 2007, 2008 and 2009. He was part of a league-record 727-minute shutout streak in 2007.
He is the league's all-time leader in goals against average (1.12) among goalkeepers with at least 10,000 minutes and third overall. No one has started more Dynamo games (170) or played more minutes (15,339) than Onstad, who announced his retirement Tuesday.
Onstad also made 57 appearances for Canada from 1988-2010, posting 21 shutouts. He helped Canada to the 2000 CONCACAF Gold Cup championship and to the 2007 Gold Cup semifinals.
