Middleton netted GB's opener
Great Britain's men will play at this summer's Beijing Olympics after beating India 2-0 in the final of the qualifying tournament in Chile.
Britain won all six qualifying games to progress, while eight-times gold medalists India failed to qualify for the first time since 1928.
The damage was done inside 10 minutes as Barry Middleton swept home and Richard Mantell's flick made it 2-0.
"We got our just rewards today," said GB team manager Pete Nicholson.
"The result was the consequence of six months of very hard work and a professional approach to this tournament.
"This was always going to be a tough match but the boys worked hard and got exactly what they deserved. We're delighted."
The men emulate Britain's women, who had already qualified for Beijing.
The event in Chile was the second of three qualifying events.
GB join New Zealand, China, Netherlands, South Korea, Canada, South Africa, Spain, Belgium, Pakistan and Australia in the 12-team Olympic competition.
