Charlton Athletic saw off League Two side Oxford United on Tuesday in their FA Cup third round reply at the Kassam Stadium.
The Addicks came away with a 3-0 win, with goals from Yann Kermorgant and Danny Green.
Oxford held Charlton to a 2-2 draw at the Valley in the original tie, and were 2-0 up at half time before two second half goals for the Londoners earned themselves a replay.
Kermorgant scored the equaliser eight minutes from time when the clubs met in the first tie, but struck much earlier in this game when in the 35th minute the Frenchman placed the ball in the net from 20 yards.
The second came soon after when Green tapped home from three yards in the 38th minute to double Charlton's lead.
The U's made a game of it in the second half but failed to convert any of their chances. They started on the front foot but couldn't maintain the pressure and soon conceded a third goal as Kermorgant struck a wonderful free kick beyond Oxford goalkeeper Ryan Clarke in the 58th minute.
Charlton manager Chris Powell said, reports BBC Sport: "Considering what we went through in the first game, I was very pleased with how we did in this one.
"The goals came at the right time and I thought we were quite clinical tonight. I'm pleased with all aspects of our play and for our fans as well."
Oxford manager Chris Wilder admits his team ran out of energy and gave away bad goals.
Wilder said: "We started well enough for the first 25 minutes and stayed competitive but gave two bad goals away.
"For the first, one of our players didn't track, and the second one was a mistake.
"We tried to get back into the game in the second half, but it was the same. We started off on the front foot and made more of a game of it, but then ran out of steam."
Charlton will now face Huddersfield Town in the fourth round at the John Smith's stadium on Saturday.
