Glasgow's hopes of reaching the knock-out stages of the Heineken Cup were all but ended by a 22-14 defeat to Newport Gwent Dragons.
Three tries before the interval gave the Dragons a healthy half-time lead as their backs produced their best performance for some time, but they were unable to add to their score in the second half as the Scottish visitors produced a late but unsuccessful rally.
The Dragons scored tries through Adam Jones, Luke Charteris and Martyn Thomas while James Arlidge struck two conversions and a drop goal.
John Beattie and Kevin Tkachuk crossed for Glasgow with Dan Parks converting both tries.
Before Will Greenwood started breaking down moves off the field, he was doing the business on it - and no match better illustrated the type of marauding centre he was than in a virtuoso performance against Wales.
