Ospreys head coach Steve Tandy sang the praises of his replacements after his side beat Edinburgh at the Liberty Stadium on Friday.
The 27-13 victory means the Welsh region moves into the top six on the table for the first time this season.
Replacement hooker Scott Otten was one of the Ospreys' heroes as he came off the bench to score a try and fellow reserves Olly Cracknell, Gareth Thomas and Aaron Jarvis also impressed with fine performances.
"Over the past three games our bench has been outstanding," Tandy told the South Wales Evening Post.
"The boys had been buzzing all week after the high of beating Munster away the previous Sunday, but with just a five-day turnaround it caught up with some of them in their legs.
"We needed a bit more energy because the week we had taken its toll.
"We've put in a 23-man shift in the games against Glasgow, Munster and Edinburgh, showing the depth we are starting to grow and what the development arm of the Ospreys is doing."
Tandy couldn't hide his delight at the result which means his side move above Munster in the standings after the Irish province suffered a 27-24 away defeat against Glasgow.
"It's pretty big for us to back up the positive performance we produced in Munster," he added.
"We had just a five-day turnaround and with all the boys we have missing through injuries and international commitments, it's a real positive focus.
"It would be easy to look at it in terms of the negatives from the first half. We contributed to our own problems then and the referee got on top of us, but that was on the back of a lot of our mistakes.
"But we turned it around and to have only a 12 percent turnover rate after the break shows how we controlled the game and managed to claw back from seven points down to win relatively comfortably."
