Mike Foley and Rich Graham's side won this match because they had complete control of the forward exchanges. They starved their hosts of possession during a first half where they were in complete control, whilst always having the ascendancy in the set piece.
Glasgow, for all their desire, simply had no response to what was a superbly organised attacking catch and drive ploy and their pack became increasingly tired as the match wore on trying to nullify the effect of the Bath eight and in particular the thunderous bursts of England second row Danny Grewcock.
Bath did not play with the fluidity of the prequel to this match, but gathered the result that they desired by scoring four tries during the match, taking their tally to thirteen in this season's competition. All four tries were well-worked and finished, indicating that the West Country outfit are playing with greater expansive ambition.
"People had tried to tell us in the build up to the two matches with them that they weren't much of a team," said coach Foley. "They proved in both legs that the theory was rubbish. They made us work tremendously hard for our victories and I regard it as a significant achievement to have pocketed the bonus point in Scotland."
Despite being subjected to extensive early pressure it was Glasgow who took the lead through the boot of Dan Parks after two minutes, but the Scotland international's effort was cancelled out by Olly Barkley's first opportunity in front of the sticks.
Bath's possession during the first period was gluttonous, but they did not cross the white wash until the dying seconds of the half, when Nick Walshe sold an outrageous dummy from the base of a ruck three metres from the line to score. By then, the visitors had failed to capitalise on a number of opportunities, but Glasgow's 'on the edge' approach to defend technically brilliant rolling mauls did not get picked up by the referee until midway through the half.
Spurred on by their opening score, Bath started the second half in dominant mood and extended the lead on forty-two minutes when the outstanding Danny Grewcock picked a wonderful line to dance his way through a couple of attempted tackles to score near the posts. Barkley added the extras and suddenly Bath had a comfortable lead.
However, any indications that Bath would cut loose were cut short, when Glasgow suddenly kicked into life throwing the ball around sevens style. At times their retention was superb, offloading in the tackle at will and forcing a high pace to boot. However, Bath's defensive effort was commendable.
Former Bath prop Kevin Takachuk did crash over the line to give the home side hope of victory, but that was as close as they were to get as young Tom Cheeseman, on for Frikkie Welsh, picked a wonderful line to outpace Scotland winger Rory Lamont for a great converted try midway through the half.
Bath though, saved their best for last when Michael Stephenson juggled with the ball after a fine attacking move to outpace the cover to touch down out wide for a try which Barkley converted to secure maximum points.
