"Devastated" ... Rotherham United's players after being hit by a late setback against Crewe Alexandra

The home side were leading 1-0 in the 89th minute of the League One clash at AESSEAL New York Stadium and set for the win their dominance deserved.

However, they conceded a penalty and substitute Chris Porter stepped up to score to give the visitors a share of the spoils.

"The lads are devastated," Warne said. "It feels like a defeat because it was one-way traffic. I am really disappointed."

Rotherham, who moved up to fifth in the table despite their late misery, had 20 attempts on goal

"There isn't a lot wrong," Warne added. "I don't think we can coach them any better or be any more organised. It's just that we didn't take our chances.

"Unfortunately we didn't get that second goal. While ever it's 1-0 the opposition are still in the game.

"Teams are going to come here, frustrate us and slow the game down. We have to be better. These games are banana skins for us."

The introduction of Porter, after a first Rotherham goal for new boy Ollie Rathbone, turned the game around as the veteran striker gave Crewe the attacking intent they had lacked earlier

He forced the first proper save out of Rotherham keeper Viktor Johansson before winning and dispatching the penalty.

Wes Harding, a half-time substitute for Joe Mattock, gave away the spot-kick and was sent off for a second yellow card.

Crewe boss David Artell, a Millers old boy, said: "I thought we stuck to our task. The players were magnificent in their application and desire to stay in the game.

"It's a tough place to come to. Rotherham are strong and physical and ask questions of you. It's a definite penalty and Ports has stuck it a way."
