Neil Aspin said his young side had to play like men to reach the final of West Riding County Cup with a 1-0 win at Ossett Town.
The Halifax boss made eleven changes to the team which beat Vauxhall Motors 3-1 a day earlier, with striker Alex Johnson netting the decisive goal.
But Aspin said he was most impressed with the youngest members of the starting line-up.
He said: “It was all about the young lads who played and I was really pleased with their attitude and commitment. They didn’t pull out of any tackles and gave some really good performances.
“Ossett were very competitive and the younger lads have had to play like men tonight to get the result. We scored a nice goal with a good bit of football.
“We were able to mix them in with a few players from the first-team who needed games. Phil Senior did well - he needed to have a game in goal. Alex Johnson’s not had a full game for a while, and neither has Jason St Juste.
“The attitude of players like Lee Gregory was excellent as well, he worked hard and I was pleased with his performance.”
The Shaymen will now face Guiseley in the final at Valley Parade at the end of the season, for which Aspin said he would not be against rewarding his younger players with another appearance.
He said: “It’s an opportunity for some of the younger lads to play at a Football League ground and I don’t want to take the opportunity away from them.
“By the time we get to the end of our season with all the games we have, it’ll be very difficult to get eleven of our regular first-teamers playing. The lads who have come in and done well so even if we have to play eleven kids from College, we’ll do that.”
