Coach Ken Hinkley relished Port Adelaide's maturity after the Power backed up a stirring victory over Richmond with a comfortable 28-point win over Carlton at the MCG.
Coming off consecutive wins, Carlton had hoped to make the Power their first big scalp but were left to rue wasted first-half opportunities as Port Adelaide gradually kicked away for a mature 15.6 (96) to 9.14 (68) victory in front of 32,893 fans.
"I was really pleased to be honest - more pleased than you'd perhaps know," Hinkley said.
"Because last week was a really big game and a really strong performance.
"Last year after that big game we didn't play the game of football we wanted to play the next week.
"To the boys' credit, led by Tom (Jonas) and Ollie (Wines), I thought they were outstanding the way they went about it."
Jonas brought the Power players together post-match and Hinkley said his captain had recognised the importance of the consolidating victory.
"We've got to be a side that over and over and over again, you've just got to keep turning up," Hinkley said.
"That's what good sides do and the very best sides in the competition have done that for a very long time - we're starting to do that."
Robbie Gray and Mitch Georgiades booted three goals apiece, while Ollie Wines (32 touches), Karl Amon (28) and Darcy Byrne-Jones (24) were typically influential and Aliir Aliir and Tom Jonas were excellent down back.
Carlton young gun Sam Walsh continued his great start to the year, racking up 29 touches and eight clearances.
Once the Power settled, they looked a class above and nudged out to a 23-point lead at halftime - though their night was soured by a shoulder injury to Dan Houston, who was substituted for Willem Drew at the main break.
The Blues never dropped their heads but were kept at arm's length and the Power effectively sealed the result when they kicked 6.1 to 2.5 in the third quarter.
Carlton's Jacob Weitering left the field in the third quarter after copping high contact from Wines but passed a concussion test and returned for the final term.
The Blues outscored the Power in the final quarter to cut back the margin, but it proved too little too late.
"There's bits you want to grab onto but I think at the end of the day we learned a lesson in terms of how clean they were with the ball," Carlton coach David Teague said.
"... Particularly through the second and third quarters we got some good looks but we couldn't get inside 50 and connect, yet when they got their looks they went forward and scored."
