Glasgow 32 Ulster 10
Ulster will return to Scotstoun on Friday night for a Guinness PRO12 semi-final after a late rally in the second half from the Scots saw them take a bonus-point win at Scotstoun on Saturday afternoon to top the standings as the regular season came to a close.
Munster secured a bonus point win at home against Dragons and also finished on 75 points, but the Scots had won a game more during the regular season to finish top.
Ospreys scored three tries in the first half of their game in Galway against Connacht but did not score a point in the second half although winning 24-20. The Welsh will go to Thomond Park next Saturday.
At Scotstoun, Glasgow won the toss but elected to play against the strong breeze and took a 3-0 lead after five minutes with a penalty from outhalf Finn Russell.
Ulster - who showed 12 changes to the side which drew with Munster a week previously - went on to dominate the half but spurned several opportunities to score.
There was concern for influential lock, Franco Van der Merwe on 19 minutes when he was taken off suffering a knee injury. He was replaced by Irish international Iain Henderson, one of several internationals on the Ulster bench.
Henderson dropped the ball close to the scoring line, but Gasgow had Jonny Gray sin-binned and Ulster finally turned the screw to go over for a try, captain Chris Henry claiming the touchdown. Humphreys landed the conversion for a 7-3 lead after 30 minutes.
Russell and Humhreys exchanged penalties before the break to leave the Ulster men leading 10-6 at the break, but Glasgow had the elements go come in the second half.
It was Ulster who started the second half better, but once Glasgow changed their front row they began to get an edge.
But it was a piece of individual brilliance from Scottish fullback Stuart Hogg who followed up his chip over replacement Paddy Jackson to gather, race past Mike Allen and slide in for the try.
Russell was unable to convert from the touchline, but the outhalf was to increase the lead to 18-10 when he converted his own try on 58 minutes.
Ulster lost Andy Warwick to the bin after 63 minutes and the Scots pressed, but Gray was held up over the line.
After further pressure from the Blues the third try came, Russell going over again after some big grunt work from the pack. He converted again for a 23-10 lead.
Glasgow secured their bonus point with a try from Richie Vernon on 73 minutes but more importantly guaranteed a home semi-final next week. Russell converted and it was 32-10.
The teams will do it all again next week!
