Crewe boss Steve Davis admitted his side paid the penalty for taking their foot off the gas in the second half as their three-match winning run came to an end in a 2-1 defeat at Tranmere.
Alex had led 1-0 at the interval thanks to a third goal in as many league games from Brad Inman and were seemingly well placed to make it four wins on the spin. However, two goals in five minutes from Max Power and Adam McGurk turned the game on its head.
"I said at half-time to keep going on the front foot, but we didn't start the second half well - or the first half - but I thought we edged it first half," Davis said.
"They (Rovers) were much better second half and came out up the pitch a little bit further, dropped a man behind. We didn't cope with Andy Robinson well in the second half - that little bit of skill and quality he's got to weave out a chance.
"I felt a draw would have been a fantastic result here, and at half time, we could have won."
Crewe took a 12th-minute lead with their first attack of the match - Inman smashing home from 12 yards. The Scottish Under-21 international, on loan to Alex from Premier League side Newcastle, reacted first and sent his effort high into Owain Fon Williams' net.
McGurk got Tranmere level after 58 minutes, leaping highest in the six-yard box to power home a fine header past Steve Phillips from Robinson's floated cross. Liam Palmer hit a post for Rovers before they did take the lead when Power curled home a delightful effort from the edge of the 18-yard box into the top corner.
Victory saw second-placed Tranmere arrest a recent slide of six league games without a win and, having been thrashed 5-0 by Swindon last time out, boss Ronnie Moore was a happy man.
"What we did at half-time was change it and go three up front and it worked a treat to be fair. For 20 minutes of the second half we had them on the ropes," he said. "Back-to-back home wins is what we want, but whether we'll get them or not is difficult.
"When teams come here, we need to get them on the back foot like we did for 15-20 minutes in the second half where they couldn't get out. Once we got the first it was a matter of how many we were going to score. I've nothing but praise for them, but there's no respite for them - they'll be in on Thursday."
