Match ends, Tranmere Rovers 1, Burton Albion 4.
Burton eased to victory at Tranmere to bolster their League Two title bid and add to Rovers' relegation worries.
Damien McCrory put the visitors ahead with a left-foot shot and Lucas Akins' tap-in doubled the lead.
A 25-yard volley from Kayode Odejayi gave Tranmere a lifeline and a foul on the striker handed them a penalty.
But Jon McLaughlin kept out Max Power's spot kick before Nasser El Khayati's clinical strike and Adam Dugdale's own goal made sure of the Brewers' win.
It was a second penalty save in as many games for McLaughlin - after doing the same in the midweek win over Southend.
It helped Burton to a fourth win in succession and their biggest away victory of the season, leaving them five points clear at the top, while Tranmere only remain out of the bottom two on goal difference.
Burton manager Jimmy Floyd Hasselbaink told BBC Radio Derby:
"We started to be too arrogant, thinking we had to do more than we had to do, taking an extra touch, an extra pass.
"We didn't have to do that. They came more in the game and scored a worldy, a good goal.
"Then you are on the back foot because you didn't do what you used to do five minutes ago. Luckily the break came when it came and we could assess a few things."
