Derby head coach Paul Warne is taking nothing for granted despite another shift in his team’s favour in the race for automatic promotion.
A 3-0 home win over Leyton Orient coupled with Bolton’s draw with Portsmouth means the Rams have a four-point lead in second place, although the Lancashire club have a game in hand.
It was vital Derby took maximum points and in front of another 30,000-plus crowd they went ahead in the 10th minute when Kane Wilson pounced at the back post from a Nathaniel Mendez-Laing corner.
Another set-piece led to the second in the 18th minute, with Sonny Bradley volleying in a Louie Sibley corner from close range.
Orient were more of a threat in the second half but the best chances fell to Derby, with Mendez-Laing failing to convert in the 61st minute after racing clear.
Sibley also went close on two occasions before Bradley sealed a convincing victory with a back-post header from another corner.
Warne said: “The lads have done well, scored from three set-pieces and we probably could have scored from open play but it’s just about winning, so I’m happy.
“It’s been a good day but all it does is give us another opportunity. With two games left it’s in our hands again but we’ve got to try and back it up with two more wins to give us a real chance to go up.
“Obviously now it gives us a much better chance, but that’s all it is so we haven’t achieved anything, but it did feel like a good day. The lads performed well. I don’t think Joe (Wildsmith) had a shot (to save).
“Some days it’s difficult to score goals. Today I watched Leeds play, they couldn’t score, last night I watched Leicester and they couldn’t score. When you are at the top of the table it’s difficult to get over the line.”
Leyton Orient head coach Richie Wellens said: “They ran all over us. They are a good team with loads of experience and they just overpowered us.
“The players have been unbelievable this year but they are probably on their last legs and we are asking too much of them with what we’ve got available. We just ran out of steam a little bit.
“The big one was the set plays. We started the game okay but after the set plays in a quick space of time it becomes very difficult.
“I think it’s something we need to improve on next year. We’ve done well but I think with set plays in this division if you can score a lot more than you concede you can get an extra 12 points.”
