Former Oakham School student Crista Cullen had an impressive games as she scored two dramatic late winning goals to keep Great Britain in with a chance.

But a frustrating goal-less draw against the USA on Monday meant GB would not qualify from their pool for the semi-finals, where the medals are decided.

It was a similar tale of disappointment for goalkeeper Alistair McGregor, the PE teacher from Knossington School.

He performed heroics for the GB men's team but they were eliminated despite a highly creditable 3-3 draw against defending champions Australia on Tuesday.

McGregor and his team-mates finish with a fifth-place play-off against South Korea on Saturday.

Crista has been through a range of emotions in the last week, from joy to despair.

Last Thursday she jubilantly flicked home a penalty corner to give GB a 2-1 win over New Zealand to keep their medal hopes alive.

Crista repeated the trick in the next match with an equally dramatic last gasp penalty corner strike to defeat Japan 2-1.

However, that draw with the States was enough to knock the team out.

Great Britain ended up sixth after losing a play-off with Australia today (Friday).

Crista had a penalty corner strike brilliantly saved before the Hockeyroos took the lead.

In a desperate attempt to snatch a draw and take the match into extra time, GB removed goalkeeper Beth Storry and Crista assumed kicking-back duties in her place.

But there was no dramatic ending as the Aussies netted a second past her at the death.
