DERBY County recovered from a nightmare start to take a 3-1 half-time lead at Blackpool.
The Rams went behind after only 15 seconds, when David Goodwillie sent a dipping 25-yarder over Lee Grant and into the net.
But Steve McClaren's men hit back instantly, in the second minute, when Chris Martin turned in Johnny Russell's low cross from the left at the near post.
In the process, Martin became the first Derby player to hit 20 goals in a season since Dean Sturridge 18 years ago, in 1996.
After a period of relative calm, the visitors took the lead from an excellent move in the 14th minute.
Russell and Martin combined to release Craig Bryson on the left and his low centre was converted by Patrick Bamford from close range.
Five minutes later, Derby added a third goal.
After Martin was fouled, George Thorne's quickly taken free kick caught the hosts napping and Bryson raced into the box to beat Matt Gilks from 12 yards.
Blackpool defender Craig Cathcart glanced a header wide from Tony McMahon's right-wing corner shortly after the half-hour.
But Derby could have had a fourth with 40 minutes on the clock.
Bryson's through ball found its way to Bamford, whose low shot was well blocked by Gilks.
