Louie Sibley scored his first hat-trick at Under-23 level as Derby County beat Leeds United 7-1 in Group H of the Premier League Cup.
Sibley's close-range finish gave the Rams an 11th-minute lead before he netted his second five minutes later.
Mason Bennett made it 3-0 for the home side before October's Premier League 2 Player of the Month Jahmal Hector-Ingram extended their lead with less than half an hour gone.
Max Bird netted a fifth goal after the break, before Sibley completed his hat-trick with a penalty that he won himself. Hector-Ingram added Derby's seventh late on.
Josh Galloway grabbed a late consolation goal but the second-placed Rams secured their first points in Group H, while Leeds are bottom with one point from two matches.

Group D
Doncaster Rovers maintained their perfect start to the Premier League Cup campaign, winning 1-0 at Aston Villa despite playing more than half the match with 10 men.
AJ Greaves was dismissed in the first half, while Villa were also awarded a penalty in an eventful opening 45 minutes.
But the hosts' spot-kick hit the post and instead it was Doncaster who came out on top thanks to Max Watters' second-half goal.
Group F
Huddersfield Town moved up to second behind Liverpool after drawing 1-1 with Wigan Athletic.
Ollie Crankshaw scored the opener for a young Wigan side that included 15-year-old debutant Alfie Devine, before Scott High's 14th-minute leveller for the Terriers.
